206: Scope Rabbit Holes With Andrew Rogue
About this episode
Andrew Rogue shares a challenging diagnostic story involving a 2017 Chevy Malibu with a persistent misfire and injector issues. The discussion dives deep into lab scope usage, interpreting injector waveforms, and the pitfalls of misreading data that can lead to diagnostic rabbit holes. They explore the complexities of injector circuits, the importance of amperage measurement, and the value of networking with other techs for advanced electrical diagnostics. The episode also highlights the balance between confidence and humility in troubleshooting and the continuous learning process in automotive diagnostics.
Andrew reached out to me to discuss a misfire diagnostic on 2017 Chevrolet Malibu. He reached a conclusion, but was left with questions on the scope results. We'll discuss the problem and attempt to clear up what was really going on. This is great example of how powerful a lab-scope can be, but also how easy it can lead us down rabbit holes.
