HOLSTEIN 2IAC0348 idle air control valve for the 1999-2004 Subaru Forester H4 2.5L and other vehicles controls engine idle speed.
A rough or surging idle, stalling as you slow to a stop, or an idle that stays too high can come from a failing idle air control valve, and from other problems too. With the engine off and cool, look over the electrical connector and the air passages at the valve for a loose fit, cracks or heavy carbon before you replace it.
The 1999-2004 Subaru Forester H4 2.5L and the 2000-2004 Subaru Outback H4 2.5L each take one of these valves. It is also an idle air control valve for the 2000-2004 Subaru Impreza H4 2.5L and for more Subaru models. Open the "Vehicles it fits" section to check your exact model and engine.
