New to this kinda of thing but really need help..i have a 2004 f250 6.0 factory as can be i haven't did anything to it mechanical wise but lately while driving the truck bogs down while Im driving. If i give it a little gas or get off the gas it will clear up or sometimes while im driving if it doesn't bog down,and Im trying to accelerate the truck will start to turbo bark..Seen alot of post on the net but no answers really need the help!!!!!!

 

We will need your scanner readout when the problem is happening. My guess would be a stuck or sticking turbo but we need your system readings so that we can rule out everything else.

 

Since your turbo doesn't have a waste gate, the unison ring helps to monitor turbo pressure. If stuck, pulling a P0299 code, you will need to pull the turbo and repair or replace the ring.
You might also check you MAP hose that runs down to the passenger side valve cove. It can crack at the valve cover nipple and lose vacuum and reek havoc on that turbo.
To Don's point, pull your data first, Ebp, baro, map, etc.

 

I would put the scanner on it but the truck isn't throwing any codes??

 

I'll pull that MAP hose and check it

 

My truck isn't throwing any codes out..

 

have you looked with a scanner though?
many many things on these trucks will not light the CEL.

 

I haven't but i will once i get off...it doesn't hurt to try

 

Also, is it blowing black smoke when it starts to bog down?

 

let me word that a little better,
if your check engine light is not on, that does not mean you have no codes.

 

Yes sir..and Im not to much a fan of black smoke coming out my tail pipe

 

I had that happen when my exhaust back pressure sensor went bad.
