In the 2001 Ford Expedition, you can locate the idle air control valve by watching a video here: https://www.Youtube.com/watch?v=abX5TlmT3Oo. The spark plugs typically last for 100,000 miles, unless they are copper, in which case they should be replaced every 30,000 miles. It's recommended to replace your air filter every 15,000 to 30,000 miles, and the coolant should be replaced every 60,000 miles. Engine issues may arise, such as loose gaskets that need tightening, spark plugs popping off, and the serious risk of engine overheating leading to fires or vehicle explosions. Keep an eye out for excessive oil consumption, which may require more frequent oil changes, and address any oil leaks promptly.
The idle air control (IAC) valve can be found on the throttle body of fuel-injected engines. It collaborates with the vehicle's ECU to electronically manage airflow to the engine for consistent and smooth idling.
