Standard Ignition Idle Air Control Valve P/N:AC224
Standard Ignition AC31 idle air control valve for the 1994-1995 Ford Mustang V6 3.8L or V8 5.0L and other vehicles lets air bypass the closed throttle to set idle speed.
A rough idle, a high idle or stalling at stops can mean the idle air control valve is worn, though a vacuum leak or a dirty throttle body can be behind them too, so find the cause before replacing it.
Standard Ignition AC31 is also the idle air control valve for the 1989-1991 Ford Taurus V6 3.8L, the 1988-1995 Ford Thunderbird V6 3.8L and the 1991-1993 Thunderbird V8 5.0L. It fits Lincoln and Mercury models too; if your car is not named here, look it up in the "Vehicles it fits" section.

Could a hunting idle or stalling at stoplights mean this idle air control valve is wearing out?
