I went to start my S2 tonight and it was only running on 3 cylinders, me and my dad traced this back to the number one spark plug, its definetly the plug as we swapped them around etc. Is there any specific make to buy new ones? or doesnt it really matter, the only reason i asked is because for my dads xr4x4 he said them some told him only to buy them from ford. Cheers Selby.
