An engine idling control apparatus, which has a throttle position sensor for detecting an opening degree of the throttle valve, and an idle switch for changing a state thereof at a predetermined throttle opening degree near a fully closed state of the throttle valve, comprises; a circuit for judging the state of the idle switch responsive to output from the idle switch; a circuit for updating a minimum value of output values from the throttle position sensor; a circuit for updating an increase compensation value to increase when the idle switch state judging circuit judges closed state of the idle switch, and for updating the increase compensation value to initialize when the idle switch state judging circuit judges open state of the idle switch; a circuit for setting a reference value to judge an idling state by adding the increase compensation value from the increase compensation value updating circuit and a predetermined offset value to the minimum value from the minimum value updating circuit; and a circuit for judging the idling state by comparing the reference value which is set by the reference value setting circuit with the output value from the throttle position sensor.
