Hey guys, Im new hear, just wanted to join up and ask some questions, I am a member on S.M.R., so I have already asked those guys , and they werent sure, so I have a 99 gt and a few months ago I blew a spark plug out of the head, first of all what caused this?, and second I fixed it with a repair kit specifically for the 4.6 engine, the car runs and drives but has a miss now, can anyone help me out on this?, the miss isnt real bad but very annoying, and it is robbing my horse power.
If anyone could help I would appreciate it, Thanks.
