Duramax Second Generation: 2004.5-2005 (LLY)
Hello I'll try to make this basic and as short as possible.
I have an 06 Duramax I've owned over a year without issue, it has an Edge system, otherwise stock.
I parked it overnight and when I started it it wouldn't rev over 1200, 800 in gear, lots of smoke. Unhooked the Edge so I can read codes...
