    How old are the plugs and wires? In need of replacing?

    You could also clear the code and move the injector or the spark plug/wire to a different cylinder and see if the misfire code follows it.

    The premium brands come pre-gapped but should be checked. 0.035 in for the 6 cyl for example.
