Abstract
Methods and systems are provided for adjusting an ignition energy provided to an engine cylinder upon reactivation from a VDE mode of operation. Ignition energy is increased by increasing an ignition coil dwell time and/or an ignition coil strike frequency. The increased ignition energy improves combustion stability during the transition out of the VDE mode of operation.
