I just had this problem on my Envoy on July 14, 2008, I called the guaranty company and they sent my truck to a chevy dealer, after 4 days they fixed. It was the ignition switch.

SOURCE: 2002 GMC Envoy is having

I ran into this concern with my 2002 and my wife ran into the almost identical problem with her 2003. this may sound silly,, but it was the clutch fan. Extreme loss of power from time to time came first. Then a roar of the what seemed like the engine when stopping. Actually cut off after it started to roar at highway speeds, and had absolutely no excelleration from time to time. Sometimes all of the symptoms completely went away. After taking mine to the dealer several times, finally they got it right and replaced the fan clutch. When my wifes 2003 SLt started doing the exact same thing as my 2002 had done, we both knew what the problem was, and the dealer did a quick fix. $600.00. Perhaps this should have been a recall feature, but never was. Everyone that I know that has an envoy, somewhere around the 72,000 and 103,000 mile mark has had this problem and have had to have the clutch fan replaced. It may sound like the vehicle is going to have to be junked,, but that is all it needs.

How to adjust idle


Should idle between 550 or 650 RPMs. If it wont stay running under 1000 RPMs there is something wrong. Idling at or above 1000 RPMs it' going to be slamming into forward and reverse.

2005 GMC Envoy 6 cyl. 125,000 miles. Added SeaFoam fuel system cleaner to gas. Now when I slow down, the engine drops RPM to 1000, then drops to 300, jumps back up, sometimes it just dies. Once I hit...


First thing to do is clean the throttle body, make sure to clean both the front side and rear side thoroughly. Also, disconnect the battery while doing the cleaning, this will reset the computer and allow it to relearn to the newly cleaned throttle body.

Air conditioner pump clutch keeps kicking on and off at low rpms, car dies.


This is caused by one of two things, the AC is low on charge (refrigerant) or the idle speed is to slow to a problem in the automatic idle speed control system.

I have a 2004 Envoy XL when you use the air conditioner or the defrost the RPMs drops and either acts like it is going to die or it does die. When testing for codes nothing came up. The only time it acts...


The throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean. Make sure to disconnect the battery while doing this procedure, this will reset the computer and allow it to relearn with a clean throttle body.

Car cuts out rpms jump around feels like out of gas then dies?


Wow, you've thrown a lot into your paragraph (rpms, going up hills, chugs, dies, when it warms up, when the A/C has been on, etc). With that said, I'll try to help you with what i know and what you said, and provide you with supporting diagnostic articles.

For the engine's cutting in rpms, incremental loss of power, see this handy diagnostic article that provides you with a list and explanation of the most probable causes:

When the car dies when it is warm and the A/C has been on, review these articles that specifically address such circumstances:
