First thing in morning vehicle won't idle. have to hold foot on gas. and runs rough till it warms up


Have you had your coolant temperature sensor changed? It might be not telling the ECU to go into phase lock when it is cold out.

Engine light is on?


Run a diagnostic test to show what codes come up. That will identify the reason the engine light came on. It will also reset the light.

I have a 2003 Envoy- GMC. Why does the reduce engine speed light come on


you need to scan you vehicles ECM, there is a trouble code stored there. depending on where you live most parts stores( such as a shucks/orielleys) will have a scan tool they will let you use if the vehicle is in thier parking lot. this should diagnose the issue, provided the battery hasnt been disconnected since then.

Suv envoy engine light on emission problem what can i do it 2007


The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.
When the Check Engine light (or Service Engine Soon) is turned on, the systems computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible system faults (the gas cap is just one of them) that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen/Oriley and Autozone parts stores (USA only) do this testing for free.

02 envoy, 6 cyl, loud wooshing noise when engine is cold. fan clutch seems fully engaged. goes away when engine warms up. is this normal or does fan clutch need replaced


Fan clutches for Envoys and Trailblazer are a problem, they go out all the time.

However, it is normal for it to do this when cold, but will only stay engaged for maybe 15 seconds AFTER you've put it in gear and have started to drive. After this, it will disengage and allow the engine to warm up faster.

If you haven't already replaced the fan clutch once, you're lucky. 2002 is especially bad for the clutches, but all years don't last long. Mine lasted 90k which is pretty long.

2007 GMC Envoy - Gas gauge showing empty and check engine light


This is a safety feature that the vehicle brings. You need to reset the E.C.U on dealership or it will keep doing it to you. It was probably caused by one single time that you did not closed the fuel cap correctly. Good luck

Rough idle only when engine is cold


check to see if the vehicle has EGR valve most of them are either elecrtronic or vacum controlled disconnect it and start it check and see if this smoothes out cause it sounds like the valve is staying open while the engine is cold if thsi solves the problem replace the valve.

secondly take a small screw driver aor a tiny hammer and tap the valve while the engine is running if it smoothes out replace the valve the valve is carbon filled and needs to be changed .
