The Idle Control Valve in Chevrolet Astro vehicles work in that it helps to control the rate at which the engine idles through controlling the amount of air that gets past the throttle plate. It operates in conjunction with the engine control unit and helps the engine not to stall during change in load. Normally the Idle Control Valve uses an electrically operated solenoid which contains a linear servo motor to control the flow through the throttle valve to sustain the correct idle speed. Various types of Idle Control Valves have been used in Chevrolet Astro models in the course of the years, with emphasis on the IAC actuator. Although these valves are in most cases extremely durable, problems such as jamming due to dirt or dust, cause erratic idling. Cleaning is among the recurring procedures that should be undertaken to maintain the proper power and performance of the Idle Control Valve to prevent a failure that requires replacement of a component.
