SOURCE: 2002 GMC ENVOY GARAGE DOOR OPENER
You have a quick fix item. There is a send code button on your garage door opener. You simply have to press that button, and within 5 secs, press and hold the button on the garage door opener (your car or other) until the opener rapidly blinks. The garage door and the opener will share info,,, and presto,, you can open by the remote opener. Take a peek at your garage door opener instructions. You can have up to three settings at one time... one for each button. I was asked if the buttons ever got the openers mixed up,, and the answer is absolutely not.

The plastic intake should have this sequence molded into it somewhere, and even the corresponding cylinder numbers in front of their respective holes. Have fun, and thanks for posting on Fixya.com

If I remember correctly if you look at the back side of the fuse cover, it should tell you what the fuses are. Also in the owners manual in the index, under fuses, it should give you a diagram of the fuse location for the acc. outlets. Good luck. The fuse should be a 20 or 25A fuse.

If it does it when idling I would suspect an IAC motor (Idle Air Control). If it is opening too slowly the added air the motor needs will not be supplied fast enough and the engine will kill.
It could be other things also but this is where I would start.
