A control system for a vehicle internal combustion engine having an intake space into which air and fuel are supplied, comprising in combination: an accelerator pedal biased to an engine idle position and operable to an engine off-idle position in response to a force applied thereto; position sensing means for sensing the position of the accelerator pedal; force sensing means for sensing the force applied to the accelerator pedal; and means responsive to the force applied to the accelerator pedal sensed by the force sensing means for supplying an air and fuel mixture to the engine in accord with the accelerator pedal position sensed by the position sensing means when the force applied to the accelerator pedal is greater than zero and in accord with an engine idle schedule when the force applied to the accelerator pedal is zero, whereby the engine operation is maintained at idle when the force applied to the accelerator pedal is zero even though the accelerator pedal position remains in an off-idle position.
