Idle Air Control Valve for GM Fuel Injection
Standard Ignition AC16 is an idle air control valve built for precise idle-speed management on select Chevrolet and Pontiac fuel-injected applications. It is a direct-fit service part for vehicles such as the Chevrolet Camaro, Chevrolet Corvette, and Pontiac Firebird, with OE-style fitment details that support accurate airflow control at idle.
Key Features
- Polymer-blended, isotropic neodymium/iron/boron magnet for accurate pintle movement and airflow control
- High-strength stepping motor for strong actuator output torque
- Shielded ball bearing helps resist environmental contamination
- Load-tested actuator for force output above actual load requirements
- Gaskets included for installation sealing
- Hardware included for installation support
- 1-port design with 4 terminals
Detailed Description
The Standard Ignition AC16 idle air control valve regulates bypass air around the throttle plate to help maintain stable idle speed on fuel-injected engines. Built with durable internal components and tested for load capacity, this AC16 idle air control valve is engineered for consistent pintle response and long service life. It is a practical replacement choice for Chevrolet Camaro and Chevrolet Corvette applications, as well as Pontiac Firebird models listed in the fitment data.
This part cross-references Delphi CV10029 for the same application.
What It Helps Fix
- Unstable or fluctuating idle speed
- Stalling when coming to a stop
- High idle after startup
- Idle speed that drops too low under load
- Airflow control issues related to the idle bypass circuit
Installation Notes
Verify the connector style, 4-terminal configuration, and 1-port layout before installation. Use the included gasket and hardware during replacement, and inspect the throttle body and idle passages for carbon buildup that can affect idle control performance. Confirm the vehicle’s emissions calibration and application details before ordering.
Quality Assurance
Standard Ignition manufactures this idle air control valve with high-grade materials and load-tested actuator components for durable operation. The internal motor design and contamination-resistant bearing support consistent performance in demanding underhood conditions.
