6.0 2005 engine lost power

[Gaston]

hi I have a problem with a 2005 F250 HD 6.0 l Truck
When we drive sometimes we have no power , there are no trouble codes
We already changed the egr valve and also the dieselfilters the engine runs good.
the car mileages is 52000 km and it have already a new turbo in 2007
i am sory for my englis but i live in the netherlands so it a litle bit difficult
i work at a lokale ford garage and we have a ford tester
can anyone help me??

The ICP sensors can go bad. This is for the injection control pressure. It might be going bad on ya and they are kind of intermitent when they act up.

Do you get any trouble codes when you hook up you tester?

[Gaston]

no i have no trouble code with the IDS tester

[Dave]

I dont know what to tell you. Something like that normally sets a code

[Clay Henry]

An ICP sensor should set a code as well.
All filters are good? Fuel, (both) and air?
Who ran codes for you? Some aftermarket code readers don't pick up all the codes.

Could be as simple as needing an oil change...6.0s are bad about that...mine needs one but I cant afford to do it...its runnin horrible!

[Gaston]

i read the codes with a original ford tester called IDS its a little laptop
all the filters are new and the oil is also changed because i have no trouble code we are thinking about something mechanical like turbo or exhaust or something like that

[Clay Henry]

Any unusual smoke?

Do you have a boost guage? Is it building boost?
