Abstract:
A method of operating an engine includes determining at least one characteristic of rough road performance based on at least one driveline characteristic and receiving crankshaft acceleration data. The method further includes comparing the received crankshaft acceleration data and determined characteristic, inhibiting the misfire counter based on the comparison, and operating the engine based on the disabled misfire detection.
