2005 GMC Sierra 2500 HD SLT 6.6L Poor Idle Quality, Misfire, MIL Lamp on, no power
I have very limited diesel experience but i know this is a common problem with this engine. I have heard there is a two wire connector somewhere that is the most common problem. Again, i have very limited experience so any details as to location of components ...
