Duramax Second Generation: 2004.5-2005 (LLY)
Hey fellas
Having some issues with the truck and not really sure what to try. The truck has 200k on it and running efi 60hp tune. The issue I am having is if I let the truck idle for 10 to 15 in the morning to warm up some times I can press the throttle and it wont even rev up won't go...
