An engines idle speed is a programmed function. We cannot directly adjust the engine idle speed on a modern vehicle. The power control module or PCM provides all adjustments to the idle speed. Though no external engine idle speed adjustments are possible, many things can and do cause problems.
The idle speed is the RPM of an engine, before we open the throttle. This is also the lowest speed at which the engine operates. When a driver releases the accelerator, the engine returns to the idle speed. If the engine fails to idle, it will die. Idling is an inefficient but necessary operating speed.
