how long ago did you do this?

have you checked to make sure there's no oil in your plug wells? it really shouldn't idle so high

Check all the little vacuum hoses connected to the throttle body; it sounds like one of them may be leaking or disconnected from where it should be going.

3 hoses on ours.  One at front going toward fuel rail gadget.  One at rear (greyish by torchlight) going to EGR valve, another at rear (black) going to a solenoid valve near dispack  which might be something to do with carbon canister.  :-/

Ours is a manual transmission btw, so may be different.

Ditto here...on mine it was the actual stop on the throttle body (screw with a slot in and a lock nut at the bottom of it; sits horizontally pointing to the front of the car.  Loosen it off, then screw it in until it just makes contact with the arm, then do the locknut back up.
