Remove the IACV, and spray the inside of it with brake parts cleaner. Let it dry out, and replace. Brake Parts Cleaner evaporates rather quickly, so it shouldn't take long.

To set the idle:
Remove the wire clip from the IACV, on the back of the Intake Manifold.
Remove the EVAP Purge Sel. Connector, Next to the MAP sensor on the TB.
Start the car, and hold the accelerator at 1500 - 2000 RPM's (It will throw a CEL)
When the engine is warm, slowly let off the gas and allow the RPM's to stabilize.
There is a flat-head screw on the Throttle Body, facing the Fuse Box. It might be covered in a silicon type material, just scrape it away and adjust the idle in 1\4 turn increments. Use the VECI labe under the hood to find the proper idle speed. For me, its 750 +/- 50 rpm's.

When you get it set correctly, shut the car off and replace all electrical connectors. Then remove the 7.5 amp fuse from the fuse box under the hood, for a minute or so. Replace, and start the car.

This is also a good time to make sure your ignition timing is set correctly. Good luck!
