Standard Ignition Idle Air Control Valve P/N:AC208
Standard Motor Products
Standard Ignition AC99 idle air control valve for the 1996-1998 Hyundai Sonata V6 3.0L and other vehicles meters the air that bypasses the throttle at idle. The engine computer adjusts it to help hold a steady idle speed.
A rough idle, stalling at stops or an idle speed that wanders can mean the valve is wearing out. These signs alone do not prove the valve is the problem, because a vacuum leak can cause the same idle trouble.
It is listed for a wide range of Hyundai, Mitsubishi and Dodge models. The 1996-1998 Hyundai Sonata V6 3.0L takes one valve, as do the 1991-1999 Mitsubishi 3000GT V6 3.0L and the 1991-1996 Dodge Stealth V6 3.0L. If your car is not named here, look it up in the "Vehicles it fits" section, where the other vehicles are listed.
