Detailed Description
The Standard Ignition AC290 idle air control valve regulates bypass air to help maintain stable engine idle under changing load conditions. This part number AC290 is engineered with a stepping motor and precision magnet assembly to support accurate pintle control, which is important when replacing a worn idle air control valve on a Ford Explorer, Ford Ranger, or Mazda B4000. This part cross-references Delphi CV10098 for the same application.
Compatible With 1998-2000 Ford Explorer, N/A; 1998-2000 Ford Ranger, N/A; and 1997-2000 Mazda B4000, N/A. The square connector and 2-terminal design should be matched to the original unit before installation.
What It Helps Resolve
- Unstable or fluctuating idle speed
- Engine stalling when coming to a stop
- Idle speed that is too high or too low
- Rough idle after startup or during accessory load changes
- Airflow control issues caused by a worn IAC valve
Installation Notes and Tips
Verify connector shape, terminal count, and mounting style against the original part before installation.
