My 2004 GMC Envoy has been having trouble idling and shut off at a stop light today. Now the check engine light is on. I had the thermostat and sensor replaced over a week ago. Any suggestions??

A common cause for stalling at idle is a "throttlebody" plugged with carbon. A simple De-Carbon service that cleans the carbon from the throttle plate and the IAC valve will almost always cure this condition. The check engine light will also give a clue to the system that is having a problem. Just because the code may be fora particular sensor, does not mean that sensor is bad. Sensor readings effect other systems in the truck. Suggest getting the codes read from the computer, and asking an exert here.......

Try the fuel filter. Sounds like the engine might be running rough due to weak fuel pressure. Its cheaper to replace, especially if it's still original from 04. Try running some injector cleaner through a couple of tanks of high octane gas.

Where,exactly, is the idle air control valve on a 2004 envoy located
It should be mounted on the side of the throttle body. But if it is bad you should also have a check engine light on and a stored trouble code for the valve.

Instrument panel light is out
what light is it? check the oil and if you have door light indicatores on the instrament panel check that all doors and boot are shut properly, check that your battery is charging by letting the car idle high then take off a battery lead if engine stops then battery not charging, you may need someone to help rev engine for you

My 2004 gmc envoy starts but shut off after 1 or 2 seconds
Is there a Security light on the dash? Does it come on when the engine stops? If so, it could be having trouble reading the ignition key code. You would need to have that checked by a dealership.

Code P0121 on 2006 GMC Envoy Denali Check eng. light on. Is starting to cut off when at stop idling. Checked wires to the TPS and look fine. Thinking about cleaning Throttle body next. Need advice.
Classic signs of idle air control not able to cope with sudden engine loads. Cleaning should resolve this. Remove ducting from air cleaner to throttle entrance. Spray with carb. choke cleaner or WD40 spray and wipe back to the alloy finish. clean the the throttle plate and push the throttle open with your fingers and clean in behind as best you can. Clean the passageways to the idle air control valve. Remove the valve and give it a thorough clean up. Reassemble and it should all be good.

2004 Envoy xl stalls when making turns
this is caused by slow engine idle speed, do the procedure below.
Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
