ABSTRACT:
An apparatus for controlling movement of a throttle valve in response to a change in the position of an accelerator pedal. The apparatus includes a control circuit powered from a power source through an ignition switch for determining a value corresponding to a setting of the position of the throttle valve. A throttle actuator is connected to the control circuit for moving the throttle valve to the determined setting. A device is provided to retain the control circuit powered from the power source until the throttle actuator returns the throttle valve to its closed position after the ignition switch is turned off.
