Keep idle speed steady and smooth out cold starts with the Standard Ignition Idle Air Control Valve AC64. It installs as a direct-fit replacement for the 1993-1996 Buick Century, 1993-1996 Chevrolet Beretta, 1993-1997 Chevrolet Cavalier, 1993-1996 Chevrolet Corsica, 1993-1996 Oldsmobile Cutlass Ciera, 1994-1995 Chevrolet LLV, 1994-1997 Chevrolet S10, 1994-1997 GMC Sonoma, 1995-1997 Pontiac Sunfire, and 1996-1997 Isuzu Hombre.
The idle air control valve meters the amount of air that bypasses the closed throttle plate, letting the engine control module regulate idle RPM during warm-up, at stops, and under accessory loads. If a worn or sticking original valve is the cause of an unstable idle, stalling, or a surging idle, this unit replaces it.
- Idle regulation: controls bypass airflow around the throttle plate to help maintain a stable idle speed.
- Direct-fit design: intended to install in place of the original valve on the listed applications.
- Signs it may need replacing: rough or hunting idle, unexpected stalling, or an idle that runs too high or too low.
