My 670 super diesel has never ran quite right. It runs decent at higher rpm's but has varrying speed at lower rps's. I have replaced the filters many times and put a pickup tube in the fuel tank. I have bleed the system many times also. When I first start it, it surges a bit. It seems that number one and two cylinders are colder to the touch than the back two.
When bleeding the injectors, when I crack number 4 at an idle the engine will die and it will not when the fromt three are cracked. I'm not sure if it is an energy cell issue, injector issue or pump issue? I'm not new to this just don't want to over think it. It seems to surge a bit more than miss but also runs rough at slower speeds, I can watch the tac bounce under 1000 rpm's.
