During deceleration with the throttle valve closed, current to the injectors is cut off to improve fuel economy at engine speeds over 850 rpm (A/T) (M/T: 907 rpm). Fuel cutoff also occurs when the engine speed exceeds 7, 000 rpm, regardless of the position of the throttle valve, to protect the engine from over-revving. When the vehicle is stopped, the ECM/PCM cuts the fuel at engine speeds over 5, 000 rpm (A/T) (M/T: 4, 800 rpm). On a cold engine, fuel cut occurs at a lower engine speed.
