Hey guys i know i haven't posted much here but i have got a serious problem an need some real help. I have a 03 G.T 4.6 with a vortech V1 supercharger, with ethanol injection kit, ( washer fluid ) SVT focus pump, 35 lbs injector's an im running 22c Motorcraft plugs, And custom tuned 345 RWHP. Well about a year ago i had a ignition on cylinder number1. It blew off the top of the piston. Well i rebuilt it an it did great for a while. Now a year later im have in some serious issues. Some of the spark plugs are collapsing. There closing up against the electrode. Well i replaced the fuel pump because it was slacking off an had a 20 lb DROP! so i replaced it tonight an installed a fuel filter, and found number 3 plug collapsed tonight. so i replaced it as well. The car did fine then after i went an got on it it started to act like it was haveing to catch up with it's self. Idk what to do any more. Can some one help?
