CAUTION:
The IAC valve may be damaged if installed with the cone (pintle) extended more than 1.10" (28 mm). Measure the distance that the valve is extended before installing a new valve. The distance from the idle air control valve motor housing to the end of the idle air control valve pintle should be less than 1.10" (28 mm). Manually compress the pintle until the extension is less than 1.10" (28 mm).
- Measure the distance between the tip of the IAC valve pintle and the mounting surface. See Fig 1. If the distance is more than 1.10" (28 mm), use finger pressure in order to slowly retract the pintle. The force required to retract the pintle of a new valve will not cause damage to the valve.
- Lubricate the IAC valve "O" ring with clean engine oil. Install the IAC valve "O" ring on the IAC valve. Install the IAC valve. Install the IAC valve attaching screws and tighten to specification. See TORQUE SPECIFICATIONS . Connect the IAC valve electrical connector.
- Perform the following IAC valve learn procedure. Turn ON the ignition, then OFF. Restart the engine and check for proper idle operation. On 3.8L, install the fuel injector sight shield.
