A method of controlling the air/fuel ratio for an internal combustion engine set a base value of air/fuel ratio control in accordance with detected engine parameters, and the base value is corrected by a base correction value in order to compensate for the error of the base value. The speed of change in the correction value in the learning control operation is increased when the engine speed is low, or for a predetermined time period after a hot starting of the engine.
