GMC Envoy A/C Problem

If A/C is on when car is started runs fine and doesn't try to die at stops. If car is turned on without A/C on and A/C is then turned on later compressor kicks in and out and motor tries to die when you stop. Pressures in A/C system have been checked and are fine and low pressure switch has already been checked and is fine.

I'd remove my idle air control (IAC) motor, and clean it & re-install to see if that helps. Use throttle body cleaner on pointed part of motor (pintle) and shaft , as well as spray into hole (port) it came out of . If it helps for a while, then start to do it again, I'd replace the idle Air control motor.

2006 gmc envoy loses power and stalls out


Take your Envoy to a competent mechanic and have it checked for OBD codes, etc. Otherwise, you are just replacing parts at random without identifying and solving the real problem(s).

I start my suv and it dies. If I start it a second time it will continue running and I can drive it. I have changed gas stations and added a fuel injector cleaner, but nothing works. It has 72563 mi


It seems that there is a delay in fuel delivery to the engine. Check the fuel filter, the most common problem for fuel delivery. Hope this helps . Moe
