A method and apparatus for controlling the rotation speed of an engine by the steps of calculating a desired value of the idling rotation speed of the engine, sensing the actual idling rotation speed of the engine, calculating the deviation of the sensed actual idling rotation speed from the desired value, calculating a data of a rotation speed control factor on the basis of the deviation, limiting the control factor to within a control range between an upper limit and a lower limit, storing a correction factor related to a value of the control factor used under a specific operating condition of the engine, calculating the upper limit and the lower limit of the control factor using the value of the correction factor, and controlling the amount of intake air or the amount of the air-fuel mixture supplied to the engine on the basis of the value of the control factor thus calculated.
