ok, here is the problem truck came in cranks like it has a damaged cylinder, but, when starts runs smooth and ids detects no missing,smokes like a train. acts as if it has an injector tip cracked.have been unable to identify the cylinder.ids with vcm 2 will not allow me to kill injectors.
also am getting codes po611, and i believe p1378.is it possible that the ficm which is original could be causing this issue?
