Keep the engine idling smoothly and steadily with the Delphi Fuel Injection Idle Air Control Valve CV10033, a direct-fit replacement for a wide range of GM and Isuzu applications including the 1985-1994 Chevrolet Astro, 1985-1988 Chevrolet Corvette, 1988-1995 Chevrolet C1500, 1986-1988 Buick Century, and 1991-1994 Isuzu Pickup. Mounted at the throttle body, it meters the air that bypasses the closed throttle plate so the engine control module can hold the target idle speed.
- Idle speed regulation: controls the volume of metered air routed around the throttle plate to maintain a steady idle.
- Warm-up and load response: adjusts bypass airflow as the engine warms and as accessory loads change, helping keep idle stable.
- Direct-fit replacement: installs in place of the original valve on the listed applications.
Signs this idle air control valve may need replacing include a rough or unstable idle, stalling at stops, idle surging, or an idle that sits too high or too low. Because those symptoms can have other causes, diagnose the fault first — if a failed valve is the cause, this unit replaces it.
Fits 60 applications across Buick, Cadillac, Chevrolet, GMC, Isuzu, Oldsmobile, and Pontiac — see the Buyer's Guide tab for the full list.
