Engine Performance problem
2005 Chevy Avalanche V8 Front Wheel Drive Automatic 62,300 miles
After replacing the gas cap already with a brand new one, we have brought our Avalanche to 3 places who all beleive there is a crack or hole in the gas line, which is why the engine light will not go off.
Could you tell me how much you think a repair like that will cost?
Thank you so much!
