The fuel filters are almost new(2 months old). I dont run any fuel treatments, should I? It really doesnt feel like the front end or alignment, I can feel it start in the gas pedal. Then it goes to the engine. As an over all the engine does have a different shake to it. Also it has a new ficm or re furbished from from last week, could it still be messed up? dunno what the other stuff is or what that small hole you were talking about is.Ill look up the EGR valve too..... btw thanks you guys either way I do appreciate it
