Keep idle speed under control with the Standard Ignition Idle Air Control Valve AC261, a direct-fit replacement for the 2001-2005 Honda Civic. An idle air control valve meters the air that bypasses the closed throttle plate, letting the engine's computer hold a steady idle during cold starts, at stops, and when accessory loads change.
