Going through any coolant? Could be a slight leak in that area causing a missfire...

Hard to really say. Maybe another bad plug LOL

i am no expert by anymeans worm but u might wanna just check the basics make sure the wire hasnt got up against the manifold burning a hole and causing the wire to arc. as adam said could be a bad plug maybe even a bad cap never had one but it could happen.
