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.

Try cleaning out the idle air control valve and EGR valve and test the throttle position and manifold absolute pressure sensors-also check fuel pressure
