  • at least one sensor which measures first engine operating data which is associated with said first firing event, and second engine operating data which is associated with at least one second firing event which occurs before said first firing event; and

    a controller which is communicatively coupled to said at least one sensor and which receives said first and second engine operating data, said controller including a plurality of neural networks which are employed by said controller to determine whether said first firing event is a misfire or a normal event based upon said first engine operating data and said second engine operating data.
