Abstract
A control apparatus for a motor vehicle detects a catalyst temperature during fuel cut. If the catalyst temperature is higher than a predetermined temperature, the control apparatus almost completely opens a throttle valve and increases an amount of intake air to thereby reduce pumping loss. If the catalyst temperature is equal to or lower than the predetermined temperature, the throttle valve is almost completely closed. Thereby it becomes possible to reduce pumping loss of the engine while preventing an excessive decrease in catalyst temperature.
