Help your engine hold a steady idle with the TRUE-TECH SMP T Series Idle Air Control Valve, part number AC1T. It is a direct-fit replacement for many vehicles, among them the 1988-1995 Chevrolet C1500 (V6-4.3L, V8-5.0L, V8-5.7L) and the 1988-1995 Chevrolet K1500 (V6-4.3L, V8-5.0L, V8-5.7L, V8-6.2L, V8-6.5L). Coverage spans engines from L4-1.8L through V8-7.4L. See the "Vehicles it fits" section for the full list of applications.
An idle air control valve regulates the air that bypasses the closed throttle plate. This lets the engine's control system adjust idle speed as operating conditions change. This part is also cataloged as a fuel injection idle air control valve and as an auxiliary air regulator.
Signs this valve may need replacing include an erratic idle, an idle that is too high or too low, and stalling when coming to a stop. Vacuum leaks, a dirty throttle body, or sensor faults can cause similar symptoms, so diagnose the cause first. If a failed idle air control valve is the problem, AC1T replaces it.
