Ford idle air control valve symptoms

The older Ford products more often use a spring-load plunger for the idle control valve. With this valve, the PCM increases duty-cycle to the magnetic coil. Increased duty-cycle moves the air valve against spring pressure. When input sensors tell the PCM to increase the engine's idle speed, the valve opens in the IAC, increasing air flow. The ...As you know, the idle air control valve reads the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at idle.
