Abstract
Methods and systems are provided for detecting cylinder misfire in a vehicle engine via a plurality of sensors, based on dual mass flywheel (DMF) operating frequency. In response to detection of a misfire event, the misfiring cylinders may be deactivated and upon confirmation of DMF operation out of a resonant frequency range, the deactivated cylinder(s) may be sequentially reactivated.
