Idling Problem

Idling Problem
I have a 99' with A/T, What would cause the idle to bounce around at 500-1000 rpms (dips and stays at 500 rpms) when coming to a stop? And it also sits and idles at 500 rpms and the whole car vibrates, but only when in drive or rev (under load) and stops doing this when put in to nuetral or park? And seems to do this more when the car is hot not cold? Oh yeah no check engine or trans lights. Thanks

Ok here we go
TPS= throttle positioning sensor
More info please. when I say hopping around I mean 500, 600, 550, 650, 500...you get the idea. If it does test/replace the IAC Have you cleaned your Throttle body? Do you have a K&n type filter?
y-pipe...if it does this after you install a y-pipe you have most likely damaged an O2 sensor.
