Right does this plug look normal, other than running slightly on the rich side. I have a parallel fuel rail setup and asked when the car was maped to have it on the rich side. All the other plugs are blackish which would indicate its running rich apart from this one plug looks to be whiteish on the tip. Is this anything to be worried about or am i being paraniod, ive had the car in bits looking at the injector which looks ok and checked all the plumbing for air leaks so im at a loss with this..
What do you guys think is it running lean on one cylinder ????
