URO GM1321517 Fuel Injection Idle Air Control Valve

The URO GM1321517 is a direct-fit replacement Idle Air Control (IAC) Valve designed to restore proper engine idle speed and throttle response on compatible GM vehicles. The IAC valve, also known as an idle speed control valve or idle air control motor, is a critical fuel injection system component that regulates the amount of air bypassing the closed throttle plate at idle, allowing the engine control module (ECM) to maintain a smooth, consistent idle under varying load conditions.

A failing or clogged IAC valve commonly causes rough idle, engine stalling, erratic RPM fluctuations, and poor cold-start performance. Replacing a worn valve with this URO unit restores the ECM's ability to compensate for engine loads from accessories such as air conditioning, power steering, and electrical systems.

Key Features:

• Direct OEM-style replacement for the original GM idle air control valve
• Electrically actuated stepper motor design for precise airflow regulation
• Restores smooth, stable idle speed and improves throttle response
• Addresses symptoms including rough idle, stalling, and erratic RPMs
• Manufactured to OEM specifications for proper fit and function
• OEM Reference Part Number: GM 1321517

URO Parts is a recognized supplier of high-quality direct replacement automotive components, offering broad coverage across domestic and import applications. Installation is straightforward and typically requires only basic hand tools. An idle relearn procedure is recommended after installation to allow the ECM to calibrate to the new valve.
