2004 envoy, runs but i changed valve cover gasket and something has been off since! low gas mileage and rough idle!was rear ended on the street and busted back bumper! needs a lot of talc but has been a good vehicle for us! will need towed i’m sure! clean tittke cons… Broken windshield, needs battery, bolt broken off from throttle body, misfire from sensor not getting hooked back up somewhere i think, 4 wheel drive cable unhooked. up until this i never had any trouble out of it, it drives great and runs like a tank, body and interior in good shape except rear bumber, worth the time if you have it to work on it
