Idle Speed Control

The idle speed control system is operated by vacuum signals and the MCU. The idle speed system raises and/or maintains the engine idle whenever high electrical loads or air conditioning compressor loads are present. The idle speed control system consists of a sole-vac (throttle positioner), an idle vacuum switching solenoid, and an idle speed relay.
