Help stabilize idle speed with the Standard Ignition Idle Air Control Valve (AC65), a direct-fit replacement for the 1994 Ford Ranger and 1994 Mazda B2300 with the L4-2.3L engine. This IAC valve regulates the amount of air that bypasses the closed throttle plate, letting the engine's control system hold a steady idle during warm-up, at stops, and under accessory loads.
- Emission-focused manufacturing: produced by a global emission-component maker, with quality control maintained from componentry through to the finished valve.
- High-grade materials: built with high-grade materials for prolonged life and strong performance, and each IAC is load tested so the actuator delivers force greater than the actual load for added durability.
- High-strength stepping motor: produces high output torque, with a shielded ball bearing that resists environmental contaminants for extended service life.
- Accurate airflow control: a polymer-blended, isotropic neodymium/iron/boron magnet provides accurate control of the pintle and airflow.
It uses a square connector with 2 terminals. Gaskets and mounting hardware are not included; consult the vehicle service information for the correct parts. Signs an IAC may need replacing include a rough, high, or fluctuating idle, stalling at stops, or hard starting — diagnose the cause first, and if a failed IAC valve is to blame, this replaces it. Manufacturer part number AC65. Country of origin: Mexico.
