Idle Speed: Swift
WARNING: This page is about a different car, the 1996 Suzuki Swift. However, it is still accessible from the selected car via links, so may be relevant.
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.
