    7.3L Power Stroke ICP Sensor Failure and the AI Skill Atrophy Debate [E242]

    Thanks to our Partners, Pico Technology, and Autel Watch Full Video Episode In this episode of Diagnosing the Aftermarket A to Z, Matt Fanslow starts with a case study on a 2000 Ford Excursion with a 7.3L Power Stroke that came in with a severe lack of power. What began as a fuel delivery problem turned into a more interesting diagnostic puzzle involving a P1280 injection control pressure sensor code, an aftermarket ICP sensor, and a fault that appeared to happen not during cranking or running, but after key-off. The case becomes a practical example of why testing under actual operating conditions matters. Static tests can pass, scan data can look normal, and a meter may never show the event. In this case, the scope captured something the rest of the tools could easily miss. Matt then shifts into a listener question about artificial intelligence, especially large language models like ChatGPT, Gemini, Claude, Grok, and others. The concern is not simply whether AI is good or bad, but whether people, especially kids, may begin outsourcing too much thinking, writing, problem-solving, and confidence to these tools. The episode lands on a recurring theme: tools are not the problem by themselves. The question is how they are used, what skills may atrophy when they are overused, and whether individuals, families, businesses, industries, and society are willing to think more carefully and evidence-first about the long-term effects. Topics Covered 2000 Ford Excursion 7.3L Power Stroke Case Study Matt discusses a 7.3L Power Stroke with a major lack-of-power concern. The initial issue was tied to the low-pressure fuel supply side. A basic fuel pressure test had passed, but it had not been tested under the actual conditions where the symptom occurred. That led to a larger point: testing at idle, key-on, or during cranking is not the same as testing under load. The vehicle ultimately had damaged pickup screens and debris in the fuel tank. Cleaning the tank and replacing the failed components solved the fuel supply issue, but another problem remained. The P1280 ICP Sensor Problem After the fuel supply repair, the truck began setting a P1280 code, related to the injection control pressure sensor circuit reading low. The strange part was that the voltage looked normal: Key-on engine-off voltage looked normal. Cranking voltage did not drop. Five-volt reference stayed stable. Sensor ground stayed stable. The signal looked fine while running. The meter never really caught the failure. The scope eventually revealed the important event: after key-off, the ICP signal voltage would sometimes dip nearly to zero. That appeared to be enough for the PCM to set the code on the next key cycle. Scope vs. Meter vs. Scan Tool This case is a useful reminder that each tool has limits. A scan tool may not refresh fast enough or may stop collecting data after key-off. A meter may technically sample quickly, but the display may not show a short event clearly. The oscilloscope was the tool that made the failure visible. The point is not that one tool is always better. The point is knowing which tool fits the question being asked. Aftermarket Sensor Behavior The aftermarket ICP sensor appeared to produce a rebound effect after shutdown. Matt compares the behavior to something like inertial rebound, a concept familiar from certain pressure pulse sensors and piezo-style tools. The OE Motorcraft sensor did not reproduce the same behavior. Replacing the aftermarket sensor with the OE sensor corrected the issue. Main Diagnostic Takeaways Testing has to match the failure condition. A fuel pressure test that passes at idle does not prove the fuel system can keep up under load. A sensor can create a failure outside the moment most people are watching. In this case, the important event seemed to occur after key-off. A scope can reveal details that a scan tool or meter may miss, especially when the event is brief, intermittent, or happens outside normal observation windows. Aftermarket parts can fail in ways that are not obvious or traditionally “failed.” The sensor was not simply dead. It behaved incorrectly under a specific condition. Listener Question: AI, Kids, and Skill Atrophy The second half of the episode deals with a listener question about artificial intelligence and whether it may negatively affect people, especially kids. Matt narrows the discussion to what most people mean by AI in everyday conversation: large language models. These tools can write, summarize, explain, organize, and suggest. That makes them useful, but it also creates a risk. The concern is skill atrophy. When people lean too heavily on AI to write, think, summarize, diagnose, or explain, they may lose confidence or sharpness in those same areas. AI Takeaways AI does not have to be viewed as the collapse of civilization, but it also should not be treated casually. The better question is not “Is AI good or bad?” It is: What happens when people outsource too much of their thinking to it? Matt argues for an evidence-based approach. Families, schools, businesses, industries, and society should be asking harder questions about long-term effects instead of simply letting the tools spread and hoping it all works out. Neuroplasticity matters here. Even if people become overdependent on AI, the brain can adapt again. Skills can be rebuilt. Confidence can be recovered. But that depends on whether people recognize the problem and choose to do something about it. Thanks to our Partner, Pico Technology Are you chasing elusive automotive problems?

  2. The Hidden Game Running Your Auto Repair Shop: When Systems Undermine Values [E241]

    The Hidden Game Running Your Auto Repair Shop: When Systems Undermine Values [E241]

    Thanks to our Partners, Pico Technology, and Autel Watch Full Video Episode Matt Fanslow continues his exploration of game theory by examining the difference between a shop’s official game and its shadow game. The official game is what ownership and management say the shop values: quality work, safety, fairness, employee support, customer care, and doing things the right way. The shadow game is what the shop’s systems, incentives, habits, exceptions, and unwritten rules actually reward. Those two games are not always completely opposed, and the gap between them is not necessarily created intentionally. Management may sincerely believe in the official game while remaining unaware of the behaviors being produced by compensation plans, workflow problems, favoritism, poor communication, broken equipment, or inadequate support. Matt looks at how employees can respond rationally to the system in front of them, even when those responses undermine the shop’s stated purpose. That may help explain dishonest, deviant, or destructive behavior, but it does not necessarily excuse it. The goal is not to pretend the shadow game does not exist. It is to identify it, understand what is creating it, and bring it into the light so the shop’s actual systems move closer to its stated values. The episode then takes a much less serious turn as Matt attempts to choose his Mount Rushmore of stand-up comedians. Richard Pryor, Lenny Bruce, Joan Rivers, and Dave Chappelle make the final cut, but not without considerable hesitation and several deserving names being left behind. Topics Discussed The difference between the official game and the shadow gameWhy stated values and actual incentives often conflictProduction-based compensation versus quality expectationsUnpaid inspections and the behavior they may encourageFavoritism, gravy work, and inconsistent enforcementSafety claims versus unsafe or neglected equipmentFront-of-house and back-of-house information gapsHow imperfect information allows assumptions to spreadLocally rational behavior inside a dysfunctional systemExplaining behavior without excusing itManagement’s responsibility to understand the real systemEmployees’ responsibility to communicate problems honestlyWhen trying to improve a workplace becomes less reasonable than leaving itGolden handcuffs and the personal cost of remaining in a misaligned organizationWhether mission statements represent actual beliefs or marketing languageMatt’s Mount Rushmore of stand-up comedians Questions Raised in the Episode What does a shop say it rewards?What does it actually reward?Do compensation and workflow systems support the quality standards discussed in meetings?Are safety problems addressed when employees report them?Are rules and opportunities applied consistently?What behaviors are employees learning from the system, regardless of what management says?How closely does the shadow game align with the official game?Who belongs on the Mount Rushmore of stand-up comedy?

  3. Why Customers Struggle to Trust Auto Repair [E240]

    Why Customers Struggle to Trust Auto Repair [E240]

    Thanks to our Partners, Pico Technology, and Autel Watch Full Video Episode In this episode, Matt Fanslow continues the conversation around game theory and economics in the automotive repair industry, focusing on one of the biggest invisible forces affecting customer trust: information asymmetry. Auto repair is a credence good service, meaning most customers cannot fully judge the quality of the work before, during, or even after the repair. A grinding brake noise may disappear after a $200 backyard brake job or a $500 professional repair, but the customer may not be able to tell whether the work was safe, complete, or performed to a professional standard. That gap between what the shop knows and what the customer can reasonably know creates distrust by default. Matt connects this to economist George Akerlof’s “Market for Lemons,” originally applied to the used-car market, and explains how the same logic applies directly to auto repair. When customers cannot reliably distinguish quality from poor work, lower-quality providers can drag down trust in the entire market. The episode then turns toward solutions: better documentation, digital vehicle inspections, before-and-after photos or videos, service information references, and clearer explanations that help narrow the information gap without trying to turn every customer into a technician. The goal is not to overwhelm customers with technical data. The goal is to give them enough context to understand what was found, why it matters, and why the repair has value. Matt also discusses how YouTube, forums, and large language models can complicate trust by giving customers information that may be incomplete, misunderstood, or flat-out wrong. Shops now have to compete not just with other shops, but with customer fear, confirmation bias, and online explanations that may reinforce distrust. Key Topics Information asymmetry in automotive repairAuto repair as a credence good serviceWhy customers often distrust repair recommendationsGeorge Akerlof and “The Market for Lemons”How poor-quality providers affect trust in good shopsThe role of digital vehicle inspectionsBefore-and-after documentation as trust-buildingUsing service information to demonstrate valueThe impact of YouTube, forums, and AI tools on customer expectationsWhy economic and game theory language matters in shop management Episode Highlights Matt explains that customers often cannot tell the difference between a good repair and a poor repair if the obvious symptom goes away. That makes trust harder to earn and easier to lose. He uses the brake job example to show how two repairs can appear identical to a customer even when one is much safer, more complete, and more professional than the other. The “Market for Lemons” idea is used to explain how low-quality or deceptive providers can create distrust that affects the entire profession. The episode stresses that documentation is not just paperwork. Photos, videos, voltage readings, service information, and before-and-after evidence are part of how shops demonstrate value. Matt argues that shops need to use economic and game theory terms because many of the answers to shop problems already exist in those fields. Without the right language, it becomes harder to find or explain the solution. Notable Quote “We’re insulating ourselves from a market for lemons.” Practical Takeaways for Shops Use digital vehicle inspections to show customers what is good, what is bad, and why it matters.Do not assume the customer understands the significance of a test result. Explain the before and after in plain terms.Show comparisons when possible: good versus bad, before versus after, failed versus repaired.Reference manufacturer service information when it helps explain why the job requires certain steps.Recognize that customers may arrive with fear, skepticism, or bad information before you ever speak to them.Trust is not built only by being honest. It is built by making honest work visible and understandable. Thanks to our Partner, Pico Technology Are you chasing elusive automotive problems?

    From Bogeys to Blown Fuses: Navigating Self-Doubt [E239]

    Thanks to our Partners, Pico Technology, and Autel Watch Full Video Episode In this episode, Matt starts on the golf course and ends up right back in the service bay, because apparently, even a decent round of golf can turn into a cognitive psychology lesson. After shooting a personally strong nine-hole score, Matt catches himself doing what many technical and mechanical specialists do every day: ignoring the accomplishment and obsessing over the shots, tests, tools, or decisions that could have been better. That leads into a discussion of discounting the positive, upward counterfactual thinking, hindsight bias, expert bias, and the curse of knowledge. The point is not to stop improving. The point is to stop rewriting reality after the fact. A two-hour intermittent short diagnosis may feel “obvious” once the problem is found, but it was not obvious when the vehicle came in. The same applies to repairs, removals, procedures, and every job where experience only becomes obvious after you earn it. Matt also closes with some listener-driven Mount Rushmore talk, including an all-time basketball starting five featuring Magic Johnson, Michael Jordan, Larry Bird, LeBron James, and Hakeem Olajuwon. Key Topics Why a good result can still feel disappointing when you focus only on what could have gone betterThe difference between honest reflection and beating yourself into the groundDiscounting the positive and how it shows up in diagnosticsUpward counterfactual thinking: “If only I had done this sooner…”Hindsight bias in the shop after the failure is already foundWhy “that was obvious” is usually only true after the factHow technical specialists can learn from a job without erasing the accomplishmentThe danger of judging another specialist’s time after you already know the answerExpert bias, the curse of knowledge, and why experience can distort how we evaluate othersGiving yourself enough credit while still getting betterListener messages and future Mount Rushmore-style segmentsMatt’s all-time basketball starting five discussion Pull Quote Options “Once you know where the problem was, it starts feeling obvious. But it wasn’t obvious when you started.” “Why can’t both things be true? That was a good find, and next time I might do it faster.” “Learning from it does not require running yourself into the ground.” “Knowing what I knew at the time, that wasn’t bad.” Thanks to our Partner, Pico Technology Are you chasing elusive automotive problems?

  5. Game Theory for Auto Repair Shops: Pricing, Competition, and Strategy [E238]

    Game Theory for Auto Repair Shops: Pricing, Competition, and Strategy [E238]

    Thanks to our Partners, Pico Technology, and Autel Watch Full Video Episode In this episode, Matt begins laying the groundwork for a larger discussion on game theory and how it applies far beyond poker tables, chessboards, casinos, or movie references. What starts with John von Neumann, poker strategy, bluffing, and imperfect information quickly becomes a broader conversation about how people, businesses, customers, competitors, and coworkers interact. Matt explains that “games,” in the game theory sense, are not just games. They are interactions where people make choices, respond to incentives, interpret incomplete information, and try to get outcomes. That means shop pricing, marketing, hiring, customer behavior, technician cooperation, and even where a business chooses to locate can all be understood through this lens. The episode touches on the difference between games of perfect information, like chess, and games of imperfect information, like poker. Matt uses poker as an entry point into bluffing, strategy, table image, and why mathematically sound behavior may involve moves that seem strange in isolation. He then connects that to real-world business decisions, where the “obvious” move, such as lowering prices because a competitor did, may not actually be the strongest response. Matt also walks through classic game theory examples like the Monty Hall problem and the Prisoner’s Dilemma. The Prisoner’s Dilemma becomes especially relevant to shop culture and business strategy because it shows how cooperation can often outperform pure self-interest, even though individual incentives may push people toward betrayal or defensive behavior. That idea becomes a bridge into behavioral game theory, which accounts for the fact that humans do not always make clean, rational, mathematically optimal decisions. From there, the conversation moves into automotive repair shop strategy. Matt discusses why competitors often cluster together, using examples like hotels, gas stations, Target and Walmart, Lowe’s and Home Depot, and auto repair shops. The point is not that a shop should always build next to competitors, but that proximity, customer behavior, friction, convenience, and visibility may matter more than the simplistic idea of “go where there is no competition.” The episode closes by encouraging listeners to start seeing shop life as a series of interactions, incentives, exchanges, and strategies. Not “playing games” in a manipulative sense, but understanding that every interaction involves expectations, investments, risks, and perceived rewards. Key Topics Covered Game theory as a way to understand real-world interactions, not just board games or gambling.John von Neumann, poker, bluffing, and imperfect information.Why poker strategy involves more than simply playing the cards.The role of Oscar Morgenstern and economic theory in the development of game theory.Why older economic models struggled with human irrationality.The difference between perfect information games and imperfect information games.Chess as a perfect-information game and poker as an imperfect-information game.The Monty Hall problem and why switching doors improves the odds.The Prisoner’s Dilemma and why cooperation often beats betrayal over time.Tit-for-tat style strategies: cooperate first, respond to betrayal, then return to cooperation.Nash equilibrium and the basic idea of making the best available decision based on known information.Behavioral game theory and why people do not always act rationally.How game theory applies to shop pricing, competition, and marketing.Why lowering price in response to a competitor may not be the right move.Why businesses often cluster near direct competitors.Shop location strategy and customer convenience.Seeing everyday shop interactions as “games” in the game theory sense. Memorable Ideas “The game” is not necessarily manipulation. It is the interaction itself.Poker is not just cards. It is incomplete information, behavior, bluffing, risk, and response.Cooperation can be a stronger long-term strategy than constant defection.A competitor lowering their price does not automatically mean you should lower yours.Sometimes the stronger move is counterintuitive.Customers may choose convenience and proximity over reputation, price, or even prior loyalty.A shop’s strategy is not just what it charges or how good it is. It is also where it sits, what friction customers face, and what alternatives are nearby. Thanks to our Partner, Pico Technology Are you chasing elusive automotive problems?

  6. The Targaryen Technician: When Shop Owners Become What They Once Despised [E237]

    May 20

    The Targaryen Technician: When Shop Owners Become What They Once Despised [E237]

    Thanks to our Partners, Pico Technology and Autel Watch Full Video Episode In this episode, Matt Fanslow uses Game of Thrones, specifically the arc of Daenerys Targaryen, as a metaphor for what can happen when a mechanical or technical specialist moves from employee to shop owner. The comparison is not that former technicians suddenly “burn everything to the ground,” but that people can start with strong ideals, endure pressure, accumulate responsibility, and slowly rationalize decisions they once hated from the other side of the counter. Matt draws a parallel between Daenerys’ journey, from abused and powerless exile to powerful ruler, and the path of a technician who opens a shop after years of saying, “If I were in charge, I’d do things differently.” At first, that new owner may try to build the kind of workplace they always wanted: better pay, better equipment, better treatment, and fewer manipulative incentive structures. But then reality intrudes. Bills come due. Tooling, software, subscriptions, payroll, benefits, facility costs, and client pressure pile up. What once looked like greed from the employee side may start to look like survival from the owner side. A major thread in the episode is the difference between explaining behavior and excusing it. Matt is careful not to justify poor management, bad pay plans, or unfair treatment. Instead, he looks at how stress, fear, frustration, and financial pressure can slowly change a person’s beliefs. The former employee who despised production-based pay may eventually install a production-based pay plan. The shop owner who wanted to buy the best equipment may eventually stop doing that when employees fail to care for it. The person who promised to never become “that owner” may wake up, or perhaps never wake up, having become very close to the thing they once opposed. The episode also touches on incentive design. Matt discusses how incentive-based pay plans can increase production, but only if the surrounding system is fair. When a mechanical or technical specialist is paid based on production, but too many external forces affect their ability to produce, the pay plan can feel like punishment. Dispatch, workflow, parts delays, bad information, poor estimating, broken processes, and uneven support can all take money out of the worker’s hands. In that environment, the game feels unfair, even if the pay plan itself is not inherently unethical. Matt argues that pay plans should not be used as a substitute for management. A compensation structure cannot do the work of leadership, communication, process improvement, fairness, and accountability. Straight hourly can work. Flat rate can work. Hybrid incentive plans can work. But none of them work automatically, and none of them remove the need for honest management and honest self-assessment. The larger point is that people rarely change all at once. They shift slowly. The language changes first. Then the justifications. Then the policies. Then the culture. Like Daenerys, the fall is not simply about one bad decision at the end. It is the accumulated effect of pressure, loss, betrayal, fear, and power. Matt closes by reflecting on Game of Thrones itself, noting that the show was among the best when it was at its peak, even if the ending remains debated. He suggests that Daenerys’ storyline may be worth revisiting not just as fantasy, but as a study in how ideals can erode when pressure, power, and isolation build over time. Key Topics The former technician turned shop owner: The episode examines what happens when someone who once criticized shop ownership suddenly has to carry the risk, payroll, bills, tooling costs, subscriptions, client demands, and employee issues themselves.Daenerys Targaryen as a shop-owner metaphor: Daenerys begins with a desire to break abusive systems, but eventually becomes capable of the very behavior she once opposed. Matt uses that arc to frame how former employees can become the kind of owners they used to resent.Explaining versus excusing: A central distinction in the episode is that understanding why owners behave a certain way does not automatically make those behaviors right.Incentive pay and production pressure: Production-based pay plans can produce measurable gains, but they also create resentment when employees are held accountable for factors outside their control.The danger of using pay plans as management: Matt argues that compensation systems cannot replace leadership, process design, accountability, and honest communication.Stress, fear, and rationalization: The episode explores how frustration, anxiety, financial pressure, and disappointment can slowly alter a person’s beliefs and management style.The slow drift into becoming what you opposed: The episode’s core warning is that becoming “that owner” usually does not happen in one dramatic moment. It happens one rationalization at a time. Quotes “When enough people make false promises, words stop meaning anything. Then there are no more answers, only better and better lies.” “We have to be able to explain things without excusing them.” “The pay plan cannot be the manager.” “You can have a straight hourly shop where production is good. You can have a flat-rate shop where people are happy. But neither one happens by accident.” “A production incentive becomes punishment when too many things outside the employee’s control take money out of their hands.” “A lot of people do not become bad owners all at once. It is slow, and then all at once.” “The danger is not just power. It is pressure, fear, frustration, and then the story we tell ourselves afterward.” Thanks to our Partner, Pico Technology Are you chasing elusive automotive problems?

  7. Normalization of Deviance: The Challenger Disaster and How Shop Standards Drift [E236]

    Normalization of Deviance: The Challenger Disaster and How Shop Standards Drift [E236]

    Thanks to our Partners, Pico Technology, Autel, and Independent Wrench Jobs Watch Full Video Episode Matt Fanslow revisits the Challenger disaster, not just as a historical tragedy, but as a case study in how standards, tolerances, and risk perception can shift over time. The common simplified story is that management ignored engineers, pushed the launch forward, and disaster followed. While that is part of the story, Matt looks at the deeper concept sociologist Diane Vaughan identified: normalization of deviance. The Challenger disaster happened 73 seconds after launch in 1986, killing all seven astronauts onboard. The failure was traced to O-rings in the solid rocket boosters that lost sealing ability in unusually cold conditions. But the broader lesson is not simply that one part failed. It is that warning signs had appeared before, yet each successful mission expanded the boundary of what NASA considered acceptable. What would have once been treated as outside tolerance gradually became normal. Matt connects this idea to the phrase, “slowly, then all at once,” often used to describe the collapse of relationships, marriages, systems, and businesses. The visible failure may seem sudden, but the conditions that made it possible usually developed over a long period of tolerated drift. From there, the discussion moves into automotive repair. Shops can experience the same pattern with ADAS calibrations, wheel torque procedures, tire repairs, safety glasses, uniforms, training expectations, and other operating standards. A procedure gets missed once. Nothing bad happens. It gets missed again. Still nothing bad happens. Eventually, the shop no longer treats the original standard as the standard at all. The absence of immediate consequences becomes false evidence that the deviation is safe. Matt uses ADAS calibration as a major example. A shop may begin by following OEM procedures after alignments or repairs, but over time, scheduling problems, delays, cost pressure, or customer pushback can lead to skipped calibrations. If no warning lights appear and no customer complains, the skipped step starts to feel acceptable. But that does not mean the risk disappeared. It may simply mean the failure has not happened yet. The episode also references tire repair liability and the John Eagle collision repair case as examples of what can happen when accepted industry habits conflict with OEM procedure. The lesson is not that every shop owner or technical specialist who drifts from procedure is malicious. The more uncomfortable lesson is that drift is natural. That is exactly why it has to be recognized and managed. Matt closes by encouraging listeners to look around their own shops and ask where tolerance has expanded without conscious approval. Are torque procedures still being followed? Are retorques still being performed? Are safety practices still enforced? Is training still treated as essential? Are customer-facing and liability-related procedures being maintained, or have they quietly become optional? Key Themes Normalization of deviance: The gradual process where unacceptable practices become accepted because nothing bad happens immediately. Challenger as a system failure: The O-ring failed physically, but the larger failure involved shifting standards, repeated warning signs, and expanded tolerance. “Slowly, then all at once” Major failures often appear sudden, but the underlying drift usually develops over time. Automotive examples: ADAS calibrations, tire repairs, torque sticks, wheel retorques, safety glasses, uniforms, training, and shop SOPs can all become vulnerable to tolerance drift. OEM procedures and liability: The episode reinforces the importance of following documented procedures, especially where safety, liability, and driver-assistance systems are involved. Not always malicious: Deviance can become normalized without anyone consciously deciding to take a major risk. Memorable Ideas “What would have failed in 1981 passes in 1986.”“The tolerance for acceptability expanded.”“It happened slowly and then all at once.”“It’s not a problem until it is, and then it’s a big problem.”“The absence of consequences is not the same thing as proof of safety.” Listener Takeaway Every shop has standards that were created for a reason. Some protect quality. Some protect the customer. Some protect the business. Some protect people’s lives. The danger is that those standards can erode so gradually that no one notices until the failure is already public, expensive, or irreversible.

    Corvette Customer Communcation Confusion [E235]

    Thanks to our Partners, Pico Technology, Autel, and Independent Wrench Jobs Watch Full Video Episode In this episode of Diagnosing the Aftermarket A to Z, Matt Fanslow tells the story of a modified 1994 Corvette that came in with a hesitation, backfire, and cut-out concern under light-load highway driving. The vehicle had already been looked at elsewhere, and the customer believed the problem was inside the PCM. What sounded at first like a computer problem eventually turned into a lesson in secondary ignition leakage, diagnostic assumptions, customer expectations, and the danger of two people using the same words to mean very different things. The episode starts with the question, “Can you test my computer?” Matt interpreted that as a request to diagnose why the vehicle was not running correctly. The customer meant something much more literal: open the PCM, test it on a bench, and determine what had failed inside the module. That misunderstanding created real tension once Matt found evidence pointing away from the computer and toward the ignition system. Technically, the case had plenty of reasons to look complicated. The Corvette was a 1994 OBD-I vehicle with an OBD-II-style connector, an aftermarket tune, a DTC 42 related to electronic spark timing, and an OptiSpark distributor system. Matt considered scan-tool access, PCM powers and grounds, tune corruption, OptiSpark signals, and even inspected the PCM itself. But the actual fix was far more ordinary: spark plugs and plug wires. A light mist of water exposed secondary ignition leakage, with arcing visible around the plug wires and spark plug area. The larger point of the story is not just that simple failures can hide behind complicated symptoms. It is that assumptions can create their own problems. The customer had one expectation. The shop had another. Nobody was necessarily acting in bad faith, but the mismatch still led to frustration, anger, and a near breakdown in trust. Matt reflects on how one better question at the beginning, “What do you mean when you say test the computer?” could have changed the entire interaction.

Sometimes it is about expectations that were never clarified.Asking one more question up front can prevent a major communication problem later.Not every misunderstanding needs a villain. Sometimes both sides are operating from different definitions. Thanks to our Partner, Pico Technology Are you chasing elusive automotive problems?
