Well iv read and read and heard bunch of stories.. Injectors were done about 100k ago. So at a idle iv noticed hazing a few months ago.. Thought it was only at running temp but it's hard to tell now with it being -0 outside .. But truck idles perfect, fuel milage seems the exact same.. I do have a banks fuel saver programmer and if I turn it up truck still blows black smoke (if that helps to know) but I run Amsoil additives for years now, I put fuel filter from wix while ago in fact not sure if that could be the issue.. (Should i change it) truck isn't a everyday truck.. I just ordered more additives from Amsoil with there centane booster was told to maybe put a full bottle of the fuel additive and full bottle of centane booster to try and brake free stuck injecter "if that's what it is?" Would that hurt if I did? Thanks and greatly appreciate any reply back!!
