Good day dear colleagues, maybe someone else has an idea, or has already gone like this before. So the case: We did a nice old-fashioned compression test on the engine above. All cylinders at 27 bar. Everything nicely assembled again, test drive, without trailer in order. semitrailers saddled up… and no power. (trailer empty) truck comes very slowly to 70 km/h. Before that everything was ok. Fuel filter and prefilter changed. Turbocharger makes pressure. Fuel line placed directly to the pump – no improvement. Fzg is a 1424LS Built. 95
