I still need to know why I have no throttle after changing the turbo. Throttle starts out low and when it gets to 2000 rpm it drops down and up. There is oil or fuel in the turbo on the egr side.

Do you have any codes?

SPN3474 FMI 31
Expert:  Cat Man replied 4 months ago.
Code 3474-31 is a loss of combustion. This indicates the regen ARD head is lost its flame. This will cause a derate and low power and soot loading of the DPF. Most often the cause of this code is a bad clogged ARD head. Once this problem is fixed the system should regen and power be regained.
Please reply back if you need more help or have more questions. I am happy to assist.

But I did not have this problem until the turbo was changed and then tried to drive it and this happened.
Expert:  Cat Man replied 4 months ago.
I understand. But if there is oil in the system it has most likely went into the ARD head. If you have a loss of combustion. The system is trying to regen due to spot loading.
You may also have oil in the DPF. You should remove the piping to the DPF and make sure it's no got any oil in it.
