ABSTRACT:
The idle air flow is adjusted by a step motor depending upon a drive signal applied to the step motor, so as to control the idling rotational speed of the engine. When the engine is under a certain operating condition during cranking, in which condition the step motor cannot be normally actuated, the drive signal is inhibited from being applied to the step motor.
