GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hello, my name is***** for the question. I am assuming this is a 6.0 liter engine? Also, how many miles are on it? Can you actually feel the misfire and if so when does it typically occur?
Thank you. I have one other question. Does your scan tool read live engine data? If it does can you tell me what the fuel trim readings are when the engine is running?
That is all I need right now. It will give me a good idea of where to start.
