This is what I could find for replacement instructions:
1. Disconnect the negative (-) battery cable.
2. Remove the air cleaner assembly.
3. Remove the Idle Air Control Valve (IAC) electrical connector.
4. Using a 1 1 / 4 in. Wrench, remove the IAC valve from the throttle body.
Before installing a new IAC valve, measure the distance that the conical valve (pintle) extends. The measurement should be made from the valve housing to the end of the pintle cone. The distance should be no greater than 1 1 / 8 inch (28mm). If the pintle cone is extended too far, damage to the IAC valve may occur when installed.
There is special cleaner that is used to clean them. It is an electronic cleaner that won't damage it.
A new one is around 40.00. I attached a picture of what you are looking for. It screws off the TBI.
