SOURCE: 2004 GMC Envoy has trouble idling

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.

SOURCE: battery removal on a 2004 GMC Envoy

The battery is on the right side behind the fuse box. You need a metric set to undo the 3 screws. Theres one that attaches to the body, one to the bar that goes along the top, and theres one on the left side below the vacuum hose and air induction. After you've taken out those three, you should lift the whole thing out(battery and shroud) together. It's hard to take the shroud off before you lift the battery out. After that, you have to pry the shoud off the battery. The two terminals in the back make it hard. Then just go to any auto parts store and they'll give you a new one.

SOURCE: cd not ajection

Welcome to the world of gm delco radios. I am a used car dealer in Canada and I deal mostly in trucks and suv's. Honestly I'd say 75% of the radios in Gm's don't work properly, the loading mechanism gets jammed when you try to eject and "check CD" appears. Unfortunately it's not the CD, and to save yourself any further heartbreak, rip the player out and get yourself a good quality Kenwood or the likes.

Could be the exhaust system hitting on something when the suspension moves. Inspect under the car and look for shiny spots that are making contact.

My 2004 GMC Envoy is experiencing some problem that sounds like its the transmission. When I accelerate the car makes an awful rattling noise and the RPMs always stay really high. I can tell me gears...


It sounds as though you are definitely having a transmission issue as well as possibly other drive line problems. You should have the vehicle inspected by a professional as soon as possible; because this could potentially be a major safety issue as well as causing further significant damage to you vehicle.

When my 2004 gmc envoy xuv is idleing i put the heat on n it stalls out.why?


Either you have a vacuum leak or electrical issue.
First Inspect all vacuum lines.
Next test engine vacuum (17-21 hg's)
If all a-ok then its electrical and you got your work cut out for ya.Have to probe the circuit to see where its shorting and what its shorting to. I don't think it will be electrical simple because you would be blowing fuses if it was. Sounds more vacuum related..... and thats worse.
