ISSUE:
A high idle RPM may occur after a highway cruise. This may be caused by the idle air control valve.

ACTION:
Check the throttle cable and linkage and, if necessary, replace the idle air control valve. Refer to the following procedure for service details.

1. Check the throttle body, throttle cable and linkage to see that it operates freely and returns the throttle to a closed position.

2. If the throttle does not return to a closed position, or does not operate freely, service as required.

3. If the throttle does return freely to the closed position and the high idle continues, replace the idle air control valve. Refer to the appropriate 1992 Car or Light Truck Service Manuals, Sections 03-04, 03-04C or 03-04A, for installation procedure.





Obtain an Authorized Modifications Decal and list the date, dealer number, and summary of alterations performed. Select a prominent place adjacent to the Vehicle Emission Control Information Decal suitable for installing the Authorized Modifications Decal.
