    02 honda f12 miss firing

    Towards the end of the summer I noticed my ski seems like it is miss firing is most noticeable at idle. what do you guys think I should change the plugs or do you think it seems more like a coil pack. And if it does sound like a coil pack is there a way to help determine which one with out replacing all 4. The ski has 380 hrs.

    thanks Nick

    Try changing the plugs first. How old are your current plugs?

    Yep...had the same thing happen. Missing at idle and changing the plugs cured it. It was extremely tough to tell which plug was fouled by looking at them.
