Engine Performance problem
2001 Chevy Avalanche V8 Four Wheel Drive Automatic
It's an 01' 2500
It's losing power upon acceleration. And it sounds like it backfires around the cat conv.
I have used fuel injector treatment but that's all I have done. SOmeone told me that it may either be the fuel pump or a o2 sensor.
