description A system and method for operating a multiple cylinder internal combustion engine having at least one actuator for controlling charge dilution of at least one cylinder and at least one spark plug per cylinder include attempting to improve combustion quality by modifying ignition energy of the at least one spark plug before modifying charge dilution of the cylinder, and modifying both ignition energy and charge dilution substantially simultaneously to establish combustion if an ionization sense signal associated with the cylinder indicates a misfire.
