    Maybe somebody will be able to help me find out my problem.
    I replaced 2 weeks ago injectors and cups. During 1 week after replacement everything was perfect, truck had power, fuel consumption Everage 8.4, everything was perfect till 2nd week:
    Low power, it feels like is trying to build power but can not due to be clogged. During start and low speed seems to be ok, but during accelerating getting slow and turbo guage is showing pressure around 30psi, average fuel consumption 5.5

    Thanks in advance

    Any ideas ??

    Fuel filter?
    Charge cooler leaking? Any audible boost leak under load?
    High back-pressure because of DPF filter?
    Fuel aeration?
    Clogged EGR?
    Air filter?
    Turbine impeller damage?

    Could be one of many things, would need more info.

    Forgot to mention, also check boost pressure/temp sensor located on intake manifold. If very sooted, replace, its very related to hp/tq output.
