Genuine GM Parts 89053319 - Idle Air Control Valve

Description

Restore smooth engine idle, resolve erratic RPM fluctuations, and eliminate stalling at stoplights with the ACDelco Gold Idle Air Control Valve (Part # 89053319 / ACDelco # 217-1806). Backed by General Motors, this premium replacement valve is precision-engineered to meet or exceed rigorous GM specifications for fit, form, and function, providing an authentic OE-level solution for late-1990s and early-2000s GM trucks, SUVs, and performance passenger cars.

The Idle Air Control (IAC) valve acts as an electrically controlled bypass channel around the closed throttle blade. Controlled directly by the engine control module (ECM/PCM), this motorized pintle valve meters bypass airflow to compensate for engine load variations—such as A/C compressor cycling, power steering loads, electrical draw, and cold morning start-ups. Replacing a gummed-up, sticking, or electrically failed IAC cures common drivability gremlins including surging idles, off-throttle hanging RPMs, and trouble codes P0506 or P0507.
