ACDelco 2173097 Idle Air Control Valve IAC

The ACDelco 2173097 Idle Air Control Valve (IAC) is an OE-quality replacement component designed to regulate engine idle speed by controlling the amount of air that bypasses the throttle plate. This precision-engineered valve ensures smooth idle performance and proper engine operation during cold starts and when auxiliary loads are engaged.

Key Features:

• OE-quality construction built to ACDelco's stringent quality standards
• Precision-calibrated stepper motor design for accurate air flow control
• Direct-fit replacement for simplified installation
• Helps maintain optimal idle speed under varying engine loads
• Controls air bypass around the throttle body for smooth idle operation
• Factory-style electrical connector for reliable connection

The idle air control valve works in conjunction with the engine control module (ECM) to maintain proper idle speed during warm-up, when air conditioning is engaged, or when power steering load is applied. This ACDelco replacement valve restores proper idle function and eliminates rough idle, stalling, or erratic idle speed issues caused by a faulty IAC valve.
