unless you let it warm up then kick the pedal (like a carb). Don't kick it and it stays there.
There has to be a TSB out there somewhere on this?
I have the EXACT same issue in my 99. It behaves in the EXACT same manner...only does it in the winter and stays pegged at 1500 until the throttle is touched. It makes no difference whether or not the defroster is on (thinking it might be related to the a/c compressor).
This past weekend it was such a nusance that I scanned for codes and there are none stored. I'm not sure what to do next....so I just deal with it...and have for 3 years and 95,000 miles.
