hi just came a member of the Clio club first one a 1.5 dci dynamique . a bought it with a misfire and was told injector .put it on two separate computers both came up with injector 1 so changed it and still the same so took the other 3 out cleaned them up swapped them around and still the same after more googling I've noticed some people are saying there coded is this just for new ones ?? and there's lots of air in the fuel lines does any one think it could be the seals defo cheapest option :S and if the seals don't come out with the injector how do you get it out that tiny hole ? thanks in advance everyone.
