Standard Ignition Idle Air Control Valve P/N:AC114
Standard Ignition AC426 idle air control valve for the 1993-1998 Toyota Supra 6-cylinder 3.0L controls the airflow that sets the engine's idle speed. A stepping motor moves a pintle to meter the air that bypasses the throttle.
A worn idle air control valve can show up as a rough idle, an idle that sits too high or too low, or stalling. Other problems can produce those signs too, so with the engine off and cool, first look over the hoses and the electrical connector for cracks, looseness or damage.
This idle air control valve is a direct-fit replacement for the 1993-1998 Toyota Supra 6-cylinder 3.0L, which takes one. This listing is one valve.
