Idle gets stuck

Good afternoon,

The idle air control valve is responsible for controlling the idle.

This valve cannot be cleaned. Only the bore can be cleaned out.

I would also check the throttle body and clean the plate very well of all carbon build up.

INSTALLATION PROCEDURE

NOTE: The IAC valve may be damaged if installed with the cone (pintle) extended more than 28 mm (1-1/8 in). 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 28 mm (1-1/8 in). Manually compress the pintle until the extension is less than 28 mm (1-1/8 in).
