2001 Saleen 4.6L Supercharger - this car sat for 2 years, I bought it and so far changes the fuel pump, put in new plugs, but other wise the car runs very well. After I changed the pugs (shortly) it started to have a misfire in of all places cylinder#2 ( under the throttle body) I though since was so hard to get the plug in that maybe I cracked it, new plug, ran good for about 25 mile then misfire again. Moved the COP to another cylinder, and that seem to be the problem. New COP car ran fine for about 15 miles and started to smell a burning smell. Pop the hood, damn things ON FIRE. Limped it home, burnt the COP and the pig tail.
Ohm'd wires out the seem to be the same as the other wires going to the other COP's. Check to see if there was a short with a continouity test, no short. Turned the key to the on position, the wires are getting 12v just like all the others going to the COP's. I thought maybe it has to do with when the car is driving, maybe there is a short intermittently so I traced the wires pack back the best I could and found only 1 spot that there could be a problem, taped it up real good and until I can get another COP and pigtail next week I won't know. ANY OTHER IDEAS FOR ME TO CHECK???? HELP I'M DIEING HERE!!!
