Power loss in Ford Transit

Hello everyone, I wanted to tell you what happens to a Ford Transit 2.4 of the 97 td of a friend ... The symptomatology is clear, it has a loss of huge power, I tell you ... you go by putting the marches and the first journey of each march does so with loss of power but not so much and reached the second half of the journey of the march (50 km/h in 3rd, 70 km/h in 4th) You have to put the next march to raise the speed ... it has the motor failure witness.

Hi Pedro1981.
You do not tell us if it presents smoke, what color, if there is a smell of burning or oil in the environment, the pressures in the indicators. Your problem can be rings, turbo, fuel but to be able to collaborate more accurately more data is needed. LUCK

Ole, first thank you very much for the attention ... tell you that the van does not present any subject of rare fumes or anything, and the pressures the truth that no idea ... tell you that it has a problem in the pump I think, because when the key is disconnected, the engine continues to walk ... they have told me that this problem in the pump can also be affecting the popcard. But the truth is that I don't know very well what is the best way to do it ... if you can help me I would thank you ..
