Upon start up of my vehicle it begins to slowly rev up without touching the accelerator and I have to turn off the ignition before the RPM's get to high. What might the problem be???

Flush out your transmission with the correct type fluid, Mopar ATF+4, and correct filter. Disconnect Negative cable, to reset computer, for at least 24 hours. Check grounding straps for PCM, ensure they are tight and clean.
This method worked on my 2003 Intrepid SE, 3.5L, Police Pkg car.
Good Luck!!

First you need to isolate the noise. You don't mention the mileage on the car. Do you have the supercharged engine? If you do, remove the belt for the super and make sure that is not the problem. If you still hear the noise approximately below or from the super area, it is most likely the belt tensioner pulley.
In my car there was a large washer over the pulley (original equipment), as the pulley wobbled on the bad bearings, it would cause a sound like a bad alternator or gear whine getting exponentially worse the faster the engine reved. Now that the part is replaced, you can barely hear the engine idle and is significantly quieter at high RPM.
My car - 2004 Pontiac Grand Prix GTP with 66,000miles.

Hi Pullerwife,

I have a few suggestions for you,

First of all, check your air filter, make sure its clean, not clogged, and doesn't need to be changed.

I don't know how handy you are, but if you are fairly handy, check the idler pulley bearings, if your not, have a shop check it out, as a last resort.

Power steering pump/fluid being low is also a possibility, but thats usually more of a lower pitched whine then what you describe.

You say once the vehicle is warmed up, the whining stops. Does Weather seem to be a factor as well?

Hope I've helped, and don't forget to rate.

I had the same problem on my 2006 Lucerne and it was the engine mount located on the front of the vehicle behind the radiator.
