Can someone educate me on what the prob could be with my 06 GMC Envoy. Engine light one, rpm fluctuates, lights dimming and battery gauge fluctuates when rpm does it. I had it check for code at autozone and it came with something about air. Before all this started my gas cap light came on 1st and I had the cap replaced. That fixed it for about 2 wks. Any clue what to do before mechanic is involved. Any help is greatly appreacited.
have the same problem?
