so this past labor day weekend on friday night i noticed my jeep was idling rough then after a while the engine light came on while driving then minutes later it started to flash which according to the manual says to pullover and have it towed which i did and on saturday the dealer said cylinder 4 was misfiring due to the plug becoming fouled.... so they replaced it with a champion plug. my question is what plugs are you guys running ? i loved the smoother throttle response from the E3's as well as the xtra 1-2 mpg..should i just replace it with another E3 or not chance it? also, what are those plug wires that people are using? those 0 ohm aftermarket ones..
