[QUOTE="Misfit_1122, post: 1463201, member: 31911"] Update..... I couldnt find the culprit regardless of which spark plug/ignition coil switch I did. Brand new oem plugs gapped to .028 (triple checked using two gap tools). Still no luck........ I finally broke down and disassembled the ignition coils and boots to remove the spring retainers inside the boot. To my surprise the entire middle portion of the spring was filled with what looked like hardened die-electric grease. I thought this was odd so I took a pipe cleaner and cleaned it out with the help of electric connector spray cleaner. So far I have made 10 back to back WOT pulls to include two hard launches from a stop all the way out to the limiter and up to 107 mph. I said screw it if its gonna blow might as well be today lmao..... The truck is pulling hard all the way through each gear and all the way up to 107..... Needless to say the truck is performing as it should and I'm glad to have found what seems to be the culprit to my constant misfire issue. Cant wait for my stg2 hardware to go on next week. Shout out to [USER=28733]@wgr73[/USER] to being right there through the whole process again. You rock man..... [/QUOTE]
