Default High Idle Issue

Hello all, I've been noticing something really strange. If I drive my car for any long distance, like constant with little stopping after about 20 miles or so when I come to a stop my idle is way up and stuck at about 1200 or 1400 on the tach. It never does it on a short distance run like to the store and back. Any ideas what this could be. Sounds like maybe a sticky TPS ?? Thanks for any help with this .. Also if I turn off the car and pump the gas pedal two times and then restart it, it's back to normal idle at about 700 ???

REWARD EXCELLENCE!

Default Re: High Idle Issue

If you shut the car off when the high idle occurs and re-start it and returns to normal, it usually indicates a bad TPS sensor, However being you have the 00-02 SOHC check also for an intake leak at the number 1 cyl intake runner where it meets the cylinder head as the intake gaskets are faulty on those engines and also could lead to a high idle situation.
