Standard Ignition AC77 Idle Air Control Valve

Idle Air Control Valve for Chrysler and Dodge

Standard Ignition AC77 is an idle air control valve for select Chrysler, Dodge, and Plymouth vehicles from 1991-1997. It is built to regulate bypass airflow at idle so the engine can maintain a stable idle speed under changing load conditions.

Key Features

• Polymer-blended, isotropic neodymium/iron/boron magnet for accurate pintle and airflow control
• High-strength stepping motor for consistent actuator output
• Shielded ball bearing helps resist environmental contaminants for longer service life
• Load-tested actuator for force output above actual load requirements
• Includes gasket and hardware for installation
• 1-port, 4-terminal design

What It Helps Correct

• Unstable or fluctuating idle speed
• Engine stalling when coming to a stop
• Idle speed that is too high or too low
• Idle quality issues after throttle closure
• Airflow control problems caused by a worn IAC valve

Installation Notes

Verify connector style, port count, and terminal count before installation. Clean the throttle body and mating surfaces, then install the included gasket and hardware to help ensure a proper seal. After replacement, clear any stored idle-related fault codes and confirm idle speed relearns correctly on the vehicle.

Quality Assurance

Standard Ignition builds this AC77 idle air control valve with load-tested components, a shielded motor bearing, and durable materials selected for extended service life and consistent idle control.
