    What plugs did you fit? NGK PFR6Q are the correct ones. The plugs are more than likely where your issue is. hth.

    Hmmm that's an odd one. I once had an issue with a new set of Gsf coilpacks on an apy overheating and a sticky spooge coming out the top of them. Maybe try a mates coilpacks to rule it out?

    sounds like the exact problem I had mine was a coilpack that only misfired under full load. Did you keep your old coils? If you can get it scanned on vcds, if not then maybe you could try swapping one of your old coilspacks on each cylinder see if it goes?

    i had the same problem.
    Water was coming in thru secundairy airpump.
    disconnected the hose on the airbox and covered the hole-> problem was solved.
