The idle air control (IAC) sensor in a 1993 Ford Aerostar regulates the amount of air entering the engine during idle, ensuring smooth operation and maintaining the correct engine speed. If the IAC sensor malfunctions, it can lead to rough idling, stalling, or increased fuel consumption. Regular maintenance and timely replacement of a faulty IAC sensor can help prevent these issues and improve overall engine performance. If you suspect a problem, diagnostic testing can confirm its condition.
