Abstract
To control the idling speed of an automotive engine, a control amount is predetermined which determines an idle air flow for providing a basic idling speed and the idle air flow is adjusted in accordance with the control amount. Also, when the engine is idling after the completion of the warm-up operation, in accordance with the difference between a predetermined desired engine idling speed and the actual engine speed attained after the adjustment of the idle air flow in accordance with a basic control amount, a correction value for compensating the basic control amount is computed and memorized such that the actual engine idling speed is adjusted to the desired speed, whereby the idle air flow is adjusted in accordance with the memorized correction value and the basic control amount in all the engine operating conditions including the idling operation.
