    No, but a crossed plug wire will. Either that or one is loose. Double check the firing order and your wires.

    I wouldn't think a vac leak from the PCV plate would cause a miss. It would run wierd but not miss I would think.

    check to see if one of the new plugs is cracked or broken.

    Can you figure out which plug has the misfire??

    If you can swap the coils around and see if the miss follows the coil. If it does, that coil is bad.

    Oddly enough, I think that might actually just be a vent.
