Is there such a thing as a P0300 misfire?
Non-professional mechanics should therefore note that while P0300 is a generic code, the actual root cause (s) of the code is often make-and-model specific. Nonetheless, while P0300 refers to faults in the ignition system, misfires, and especially random misfires, are often caused by faults that may not be directly related to the ignition system.

If you find trouble codes, other than P0300, stored in your computer memory, try to fix those codes first since they may be the source of the misfiring problem. A leaking EGR valve can lead to a random misfire. Photo courtesy of Towel401 on Wikipedia.
What does the last number in p0302 mean?
The last number in these accompanying codes refers to the affected cylinder. A P0302, for example, indicates a misfire on a particular cylinder (in this example, cylinder 2).
