It installs as a direct-fit replacement for the listed applications — including the 1988 and 1994-1995 Ford Cougar, 1992-1995 Ford Crown Victoria, 1997 Ford Explorer, 1996-1997 Ford F-100 Ranger, 1992-1995 Ford Grand Marquis, 1994-1995 Ford Thunderbird, 1991-1995 Lincoln Town Car, 1994-1995 Mercury Cougar, and 1992-1995 Mercury Grand Marquis (see the Buyer's Guide tab for the full list).
- Idle-air management: Regulates the amount of air bypassing the closed throttle plate so the engine holds a controlled idle speed.
- Electronically controlled: Responds to commands from the engine control module to raise or lower idle as operating conditions change.
- Direct replacement: Designed to install in place of the original valve on the listed applications.
Signs the idle air control valve may need replacing include a rough or unstable idle, stalling as the throttle closes, hunting or surging idle, and hard starting. These symptoms can have other causes, so diagnose the source before replacing — if a failed idle air control valve is the cause, this AC56 replaces it.
