PURPOSE:To prevent increase of the number of revolutions of an engine, by a method wherein, in a device which performs rapid warming-up control through which retard correction is made on an ignition timing during the starting of cold down, upon completion of raid warming-up control, retard correction is rendered ineffective. CONSTITUTION:When an idle running state is detected by a running state detecting means A, an intake air amount regulating means B is controlled a feedback control means C according to a deviation between the number of revolutions of an engine and a target value, and feedback control is made on an intake air mount. When a specified idle running state is detected correction is made by an ignition timing correction means E when an ignition timing is delayed than that available during normal idle running. In this case, during release from ignition timing correction made by the correction means E, a feedback control amount by the control means C is rapidly corrected in a direction, in which an intake air amount is decreased, by means of a feedback control correction means F.
