yeah, check into you're coil pack then. I would give you my other one, but I replaced it with the accell one because it was defective. I would get a random misfire pas 4K rpm's. My origional coil pack died and quit firing one of the cylinders completely. I replaced it with a ford one which after a month started giving me random misfires on more humid days. Then I replaced it with the accell one... That one made me really happy
