i have a 04 f250
The symtoms is
1 lack of power
2 miss firing
3 engine stop workin when idiling or even when cruising on 40 kph
4 alot of black smoke before the turbo kicks in

What i have done untill now
1 changed the fuel fters
2 cleaned the egr
3 cleaned the fuel tank(and there was alot of mud)
4 i just bought an airdog (still didnt install it)
5 thinking of removing the cat conv

Ive been in my dealer and what he said is electric problem

So guys what should i do

[jackinggear]

fix the electric problem

Did they specify what kind of electrical problem it was?

did they check your injectors?

Excess fuel could be causeing you to run really rich causing black smoke. When the turbo spools up you are getting the additional air required for combustion hence why you no longer see the smoke. Just a thought, i could be totally wrong.

I dont think your cat has anything to do with the smoke all though it is probably getting hot as hell from the unburnt fuel passing through your exhaust.

No they didnt specify they were sudgesting the ecu
And no they didnt check te injectors bcz it will cost me 1300$
Just to remove them

[jackinggear]

shouldnt cost that much to see that they are functioning properly. My friends a mechanic and used a snap on scanner(i believe) to check them. I think you should get a second opinion.

Welcome, this is the first thing you should do........Write Up: Monitoring the 6.0L PSD.

First, I would stay away from that dealer. They should have been able to run a contribution test. The scanguage II is a great monitor for diagnosing, at $160. Pull your fuel filter up top and cycle the key to see if fuel is getting up top. Make sure you are running only motorcraft fuel and oil filters with caps that match. Fuel starvation to the hfcm has a high probability of damaging the hfcm. Does the truck have an egr cooler. It seems your turbo may be sticking also. How long have you had the truck, and was it running well for you before the fuel problem?

Sent from my phone that somebody didn't help me get.

^^^^Great advice right there. Get a monitor on there so we can see what you are dealing with. There are WAY too many things it COULD be without getting some instrumentation on it. (Also, I fully agree with finding another dealer because that tech doesn't know what he's talking about.)

^^^^X3 Purchace yourself a Scanguageii and set up the X-Guage portion for the 6.0 and you can get a good idea of whats going on with the truck. I have said it a few hundred times but here it goes again: A ScanguageII is the best money you will ever spend on your truck period hands down!! Most of us are using it and I put mine to the far left of the steering wheel just below the dash area and I am the only one who can see it. Didn't like the thing in the instrument panel by speedo which is a popular location.
Don't want anyone to think I am concerned with the engine values being I am a proud 6.0 owner and feel it's a great engine when maintained. Actually I have had my truck since new and it has been bullet proof, no stiction no nothing runs like day 1 @ 75,000 miles now, spent a fortune on maintenance though. lol
Blahh Blaaa Blahhh; Get a ScanguageII MUST HAVE ITEM................

[fahhad]

How can the scanguage ii help me with this problem?
The rpm sometimes goes up and down when idiling or even cruising but(b4 the turbo kicks i.)
Would it b
1 air flow sensor
2 map sesnor
If it exist in deisel engine like petrol engines

[fahhad]

You need a Scangauge so you can check dtc's.
