Question about 2006 GMC Envoy Denali

Open Question

My 2006 GMC Envoy is chugging while I drive it. The check engine light is on steady and now the reduced engine light comes on. This seems to be reset if i remove gas cap but does not fix the problem

Does this sound like an expensive fix?

SOURCE: 2006 GMC Envoy XL gas gauge reads empty

The sulfur content in the fuel is contaminating the contacts of the sending unit.

Some people have had good luck with some fuel system cleaners solving this problem. The cheap stuff doesn't seem to do the job.

Not that GM isn't completely exonerated from fault but the gas stations don't do a very good job of watching what the stations sell.

SOURCE: gas gauge not woking properly gas tank only accepts a little gas

I had the same problem. My gas gage would read full and as I drove the gage would read empty; even when I had a full tank of gas. All I had to do is buy a new gas cap... yes that is all! $15.00 and a day later the gas gage is fixed.

SOURCE: 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

SOURCE: 2006 GMC Envoy XL gas gauge reads empty after

It is most likely your fuel level sending unit has gone bad. It sits inside your fuel tank to tell the fuel guage how much gas you have in the tank.

The sending unit for the gas gauge is in the fuel tank and part of the fuel pump module, it is not sold seperately. Price is around $350.00, 2 hours labor to install the part.

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.

Is there something wrong I have a 2006 envoy the orange motor just lit up as I was driving is there a problem with my truck?


That is the check engine light and it means that the computer has detected a problem in the engine performance. If the check engine light is flashing, you need to stop driving the vehicle soon and have a technician diagnose the problem. If the light is on steady, you still should have it looked at but it is not a critical situation.

Battery replaced and now A/C vents front blowers don't work, only floor blowers work. Lights dim, battery gauge flickers down when truck is idle. Check engine light comes on steady, then goes off...


The exact same thing happened to me... my lights don't flicker but my A/C is having the same exact issues.... if you find out what happened please let me know as well.

The reduced engine power light has been coming on in my 2003 Envoy


1st things first, clean your throttle body with throttle body cleaner. Clean it with the battery disconnected. When finished, drive around for 5 or so miles to reset the computer. The butterfly in throttle body is probably sticking. The throttle body must be nice and shiny when finished.

What does reduced engine power light mean and have no acceleration. Turned truck off and reduced engine power went out and everything is ok again; however afraid to drive the truck anywhere now. 2004 GMC...


this model has what they call fly by wire.. no accelerator cable. If the computer detects a problem in the thottle system it will not allow the engine to accelerate and will show reduced power and possibly set a check engine light. The dealer usually wants to replace the throttle assembly which is very expensive and usually un nessesary.
I have had a lot of succes with just cleaning the throttle plates real good.
