A method of controlling fuel injection in an engine of a vehicle having an all wheel drive or 4&#xd7;4 system comprises restricting deactivation of the fuel injection during some deceleration conditions when the vehicle is in an all wheel drive, or 4&#xd7;4, low gear. According to another aspect, a method comprises restricting deactivation of fuel injection during deceleration operations under all wheel drive, or 4&#xd7;4 low gear operation; and disabling the fuel injection during at least some deceleration operation under other conditions. Disabling deactivation in an all wheel drive or 4&#xd7;4 low gear allows a more controlled drivability at a time when any torque disturbance may be magnified and more easily felt by the vehicle driver.
