In the system, first and second fluctuation value of the wheel rotation speed are calculated based on a signal, outputted by a wheel speed sensor, indicating a rotation speed of the vehicle wheel, and a parameter indicative of a degree of wheel rotation speed fluctuation is calculated by multiplying the calculated first and second fluctuation values.

With this, it becomes possible to reliably avoid false detection of misfire while ensuring that misfire detection is not erroneously disabled when misfire does occur.
