Abstract
Methods and arrangements for transitioning an engine between a deceleration cylinder cutoff (DCCO) state and an operational state are described. In one aspect, transitions from DCCO may begin with reactivating cylinders to pump air to reduce the pressure in the intake manifold prior to firing any cylinders. The number of pumping cycles, if any, is based on intake manifold absolute pressure (MAP).
