Replacing throttle body today to see if that solves it. Out of town and not sure if I should drive it 100 miles to home. It had stuck at 3000 rpms the first time I noticed it and turned it back off. A/C not working either SES light on, no codes though.
How did you check code's ? OBD2 scan tool ? There are more computers on your vehicle then just the PCM/ECM - engine computer . BCM - body control module , Air bag module , ABS - anti-lock brakes , instrument cluster etc.... Need a factory scan tool or someother professional type scan tool to read these codes. If the check engine (SES) light is on code's are stored in one of these other modules . Your best bet mite be to have a qualified repair shop check it out .(not dealer )

there are a couple of things to look at. first take a look at the tempature controll sensor, its on the right side of the block. It kinda looks like a spark plug sticking out the side of the block. If its cracked or broken then it will mess with your idle. Also you should be checking your throtle body control censor and your throtle body. clean everything out. also the BWD Ignition Module/Control Unit. If its cracked it will cause this exact problem. I would also add a general tune up with spark plugs and wires. If you follow these directions I think you will be good, if this does not work let me know, I can give more info once I have a better idea.

Hate to be the bearer of bad news but mine failed at 29K and became undriveable at 31K and after years of hard handling, I treated that car like it was Christmas tree ornaments, fully expecting it to last until I am dead; the engine failed at 57,600. It's gone and I'm still breathing. It was the last GM anything I will ever own.

Replace the transmission and sell it...These vues 2003 and 2004 with the varitrack trannies were junk you may be eligible for a class action lawsuit if you live in a state where they have filled it.

I had the exact same problem on my 04 GC. I put some Techron Concentrate Plus Fuel System Cleaner in from Wal-Mart and it seemed to fix the problems right away. Let me know.
