Abstract
Apparatus for preventing undesirable reduction in the speed of an engine after starting and including an actuator operable upon engine starting to correct throttle opening to a determined extent in increasing direction, a vacuum power system for the actuator and a switching control circuit for detecting engine starting and predetermined running states of the vehicle and engine to keep the actuator energized as long as the engine speed and the vehicle speed are both below respective preset level. Even after the preset level of vehicle speed has been exceeded, the actuator is also energized in the presence of battery load, such as air conditioning or headlights when the engine speed remains below its preset level. The actuator is de-energized when the vehicle speed exceeds its preset level in the absence of battery load as well as when the preset level of engine speed is exceeded.
