Ok so I wasn't sure if this belongs in advanced or oem, I have a random occurring misfire on cylinder 2(as far as I know only #2). It originally only seemed to happen in the rain, which didn't bother me much all my vehicles had issues during storms, but even lately on the dry days it misses from about 1000rpm to just above 2500rpm then it runs smooth. I did see spark arcing across the tube the plug sits in on cylinder 2 but I pulled the wire and plug, and saw nothing related to the arc, no cracks, no heat marks, no type of carbon buildup. But on the plus side it was a nice strong spark. And again if this is in the wrong section I apologize.
