ok well ive changed sprk plugs, and just rang GSF they will take coilpacks back as long as they not fitted. going to buy another 3 and fit them 1 by 1 and see how many coilpacks have gone.. if thats not it then i have no clue whats up with this engine.

the spark plugs seem to have made misfire worse but then again it cud be the weather
