How do you adjust the idle speed on 2002 Taurus?

To adjust the idle speed on a 2002 Ford Taurus, first ensure the engine is at normal operating temperature. Then, locate the idle air control (IAC) valve, which is typically mounted on the throttle body. You can adjust the idle speed by either cleaning the IAC valve if it’s dirty or replacing it if it’s malfunctioning, as the idle speed is generally controlled by the engine's computer rather than manual adjustment. Always consult the vehicle's service manual for specific instructions and specifications.
