Idle Speed

WARNING: This page is about a different car, the 1997 Suzuki Swift. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: DO NOT attempt to adjust throttle stop screw to adjust idle. Throttle stop screw is factory-set and is used as zero reference point for all other adjustments.

NOTE: DO NOT adjust idle speed in areas above 8200 ft. elevation.

NOTE: Idle speed is NOT adjustable manually. If idle speed is not within specification, inspect related components.

Idle speed is controlled by PCM using an Idle Speed Control (ISC) actuator. ISC actuator contains a DC motor and idle switch. PCM controls how much ISC actuator plunger extends, controlling idle. Idle switch is energized when plunger contacts throttle lever screw. Throttle lever screw is preset at factory and not to be adjusted.
