• Load-tested actuator for added durability under operating conditions
• Shielded ball bearing motor construction to resist environmental contamination

Detailed Description

The AC15 is engineered for vehicles that rely on electronic idle air control to regulate engine speed at startup, during warm-up, and when accessory loads change. Standard Ignition uses a polymer-blended, isotropic neodymium/iron/boron magnet and a high-strength stepping motor to help maintain accurate airflow control. The result is consistent idle regulation for service replacement on many GM compact cars, sedans, vans, and light trucks, including Chevrolet Astro, GMC Safari, Pontiac 6000, and Oldsmobile Cutlass Ciera applications. This part cross-references Delphi CV10000 and Dorman - HELP 76031 for the same application.

Common Issues This Part May Resolve

• Rough or unstable idle speed
• Stalling when coming to a stop
• High or low idle after startup
• Idle fluctuation when accessories are turned on
• Airflow control problems related to a worn idle air control valve

Installation Notes and Tips

Verify connector shape, terminal count, and port configuration before installation. Clean the throttle body and mating surfaces, and replace the gasket if the original seal is damaged. After installation, clear any stored idle-related fault codes and allow the engine to relearn idle strategy if required by the vehicle.

Quality Assurance

Standard Ignition manufactures this idle speed regulator with high-grade materials and load-tested components to support long service life and consistent operation. The AC15 is built for accurate idle air control performance across the listed fitments, including Chevrolet Aveo, Pontiac G3, and related GM applications.
