After making a general on the engine nisan patrol 2.8 tdi (first special, new pistons, new head, new turbocharger and all possible grinding) I have a problem when I go uphill that the car barely starts at low revs. It only starts well when I give it gas to open the turbocharger. In addition, the bosch pump was in service. Can someone help me with what else might be a problem or is it generally a car lazy at low revs, but again I don’t believe it can pull itself uphill. Note I talk when the car is in 2H, and when it is in 4L then it goes but the sieve I think is still weak.
And I just forgot to say that it's not just about the start, but when it starts, it's the same slow spin and especially in 2. gear
