Standard Ignition AC79 Idle Air Control Valve

Idle Air Control Valve for Ford and Mercury

Standard Ignition AC79 is an idle air control valve for select Ford Taurus and Mercury Sable applications from 1996-1999. It is built to regulate bypass airflow at idle so the engine can maintain a stable idle speed under changing load conditions.

• 2 blade terminals for direct electrical connection
• Uses a polymer-blended, isotropic neodymium/iron/boron magnet for precise pintle movement
• High-strength stepping motor for strong actuator output torque
• Shielded ball bearing helps resist environmental contamination
• Load-tested for actuator force above actual load for added durability

What It Helps Address

• Unstable or fluctuating idle speed
• Stalling when coming to a stop
• Idle speed that is too high or too low
• Idle quality changes when accessories place load on the engine
• Airflow control issues at closed throttle

Installation Notes

Verify the 2-terminal blade connector style and confirm vehicle application before installation. Clean the throttle body and related air passages during service so the replacement idle air control valve can operate against a clear airflow path. For Ford Taurus and Mercury Sable idle air control valve replacement, match the part to the listed year and model exactly.
