"Urgent" Chevrolet Luv

PROBLEM WITH CHEVROLET LUV

Hello friends: Cheer:
Well I will tell you that I have a Chevrolet Luv Gls 2.8 Turbo Diesel year 2002.Motor 821533
Problem:
Loss of power in low speeds (eg stopping at traffic lights, outputs with rapid slopes and braking).
The low to 0 revolutions and it stops the engine and costs to turn it on again.

Maintenance:
1 ... Fuel pond cleaning
2 ... Change of fuel hoses
3 ... Change of the fuel filter bombing
4… Injector change

information: in high road speed it works well
so as not to have problems I keep the revolutions high.

The first thing is to verify with scan the existing fault codes in the memory of the aboard computer, it is necessary to confirm the functionality of the accelerator position sensor since this sensor produces this type of failure and it is confused with lack of fuel feeding, I hope that this data will be useful, greetings and luck.

Thanks reamecanic, for answering I will be very present

Resolved:
dirty injection pump
