hello im new here ,but figured i would see if anybody could help me . I have a 02 grand prix with the 3.1 im it ,and it blew a head gasket early this week ! well i bought the head set ,and tore it down . took the head to be checked cleaned and surfaced . it was fine . so i put it all back together following all tourque specs and what not . When i was done the car fired rite up ,but has a terible miss to it ! i double checked all my plug wires and they are correct i have new plugs . i went back and double checked all my wires and it dont appear that i missed any of them . so do any of you guys have an idea ?
