Check / replace fuel filter. Baka barado na ito, o baka pinapasok ng hangin ang fuel system. Kelan yung huling fuel filter replacement?

engine is 4d56 NA in a mitsu L3FB ... problem is ... upon running for a few meters and slowed down or stop, engine shakes heavily that I need to rev the engine higher to keep the engine running ... failing to step on the accelerator pedal would cause the engine to die ... I used to experience this engine behavior when I'm low on diesel but now I am experiencing it even on half or full tank of diesel ... performed the following already: fuel filter check (it's clean/unclogged upon disassembly), fuel lines check (no fuel leak or air getting into fuel lines) ... currently, the engine emits a moderate amount of black smoke when revved. Do you think that the "engine shaking" might have something to do with the injection pump's or injectors' condition?

Let me know your thoughts sir. I would really appreciate them.

Thank you.

What's your engine mileage?

It could be a fuel filter or an injection pump problem.

it's rather an old engine and was rebuilt twice already ... the last one being in December of 2009 ... according to the former owner, the last time the injection pump was checked was more than five years ago ...
