ok, I have arching, but its at the end of the spark plug wire on the plug. I ran the car in pitch black and can see a blue circle around the spark plug where the boot ends on the plug. I just put in new plugs (AGSF32C) and new wires (FMS) and I'm getting the circle arch problem at cylinders 4/3/7/8, a little bit on the others, but not nearly the full circle that occurs on those cylinders. I'm not sure if its my wires, but they dont cover the plug completely, they stop right at the word Motorcraft on the ceramic. I know they are on all the way, so thats not a problem, but what could be causing this? Also, my entire passenger side power is low, my lights are dimmer than the drivers side, and I get a LOT more valvetrain chatter on the passenger side. Is it possible (i'm a newb if there ever was one) that I'm not getting a full spark on the 1-4 cylinders and its causing the fuel in my oil? ANY input or ideas would help me out greatly, and yes I've searched and searched, but havent really found anything like my particular problem.
