Sounds like a stuck IAC (idle air control) valve...It's the sensor other than the TPS on the side of the throttle body...
Make sure there is obviously no physical restrictions like the throttle cable being jammed or stuck...

OK, is it always at 1500rpms or higher?...It's not sitting on the idle screw, right?...
What happens when or if you disconnect the IAC while the car is running?...
Are you getting any trouble codes?...Have you tried disconnecting your computer and reseting your computer?...
EDIT~What is your TPS voltage at idle?...
