Engine Mechanical problem
2006 GMC Envoy 6 cyl Four Wheel Drive Automatic 69298 miles
hi my name is robert m. Corzo
My mother Maria bought a envoy about two years. I had 2 sensors replaced 1 for the front wheel driver and 1 for the gas gauge sensor. Now I have a problem with a my check engine light on. Per my mechanic I have an idle problem, don't know if it is from having my gas cap on wrong or if there is another reason I'm having an idle problem.
