   well what can i say my luck with cars goes from bad to worse!
   got my 106 last saturday and seems dead already.... Its a 106 quicksilver converted to GTi
   driving it the other night when it suddenly started missfiring, then it cleared and went perfect for a couple minutes. Then missfired on 2 cylinders, down to 1 cylinder and cut out. After a while i got it stared and managed to nurse it home.
   Yesterday i got new plugs and coilpack but no luck! exactly the same.
   Ive had the rocker covers off to check the rockers and they all seem fine. I have even drained the fuel and put new fuel in to see if i had put in duff fuel.
   Some help please! im thinking injectors or inlet manifold? Hopefully not wiring

   It won`t hurt to do a compression test either.
