ABSTRACT:
A misfire detection apparatus and method is provided for detecting misfire in cylinders of an internal combustion engine in a motor vehicle. The method includes sensing ionization current through spark plugs in either a distributorless ignition system or a distributor ignition system. The method also includes disabling ionization current sensing during ignition coil discharge time. The method further includes making and storing the combustion ionization measurements in order to determine if a misfire has occurred and if catalyst damage has occurred due to the misfire.
