Detailed Description

The Walker 215-1003 idle air control valve regulates bypass air around the throttle plate to help maintain a steady idle during cold starts, accessory load changes, and stop-and-go driving. It is a direct-fit service part for many 1990-1996 applications, including Chevrolet C1500, Chevrolet S10, GMC K1500, GMC Safari, Isuzu Pickup, and Land Rover Discovery. If your vehicle is showing idle fluctuation, stalling at stops, or inconsistent idle speed, this component addresses the idle air control circuit directly.

Compatible With 1990-1995 Chevrolet C1500, 1991-1995 Chevrolet S10, 1991-1995 GMC Sonoma, and other listed applications, the 215-1003 supports accurate idle response across a broad range of fuel-injected trucks, vans, and SUVs.

What It Helps Solve

• Rough or unstable idle
• Stalling when coming to a stop
• Idle speed that hangs too high or drops too low
• Cold-start idle complaints
• Idle changes when electrical or A/C loads are applied

Installation Notes and Tips
