'09 Chevy 2500HD 6.0 Misfire | Finding the Real Problem

In this video, I take on a 2009 Chevy 2500HD with the 6.0L V8 that was towed in for a serious misfire and flashing check engine light. Another shop with a seasoned mechanic—over 50 years of experience—wasn’t able to track it down. Now it’s my turn to dig in, find the real issue, and hopefully get this truck back on the road where it belongs. #Chevy2500HD #MisfireDiagnosis #MechanicLife #CarRepair #CheckEngineLight #GM60L #TruckRepair Want to support us AND get early access to the SMA videos as they are uploaded?
