So on the way home my 08 250 starts to lose power and it gets a mild vibration in the engine along with a weird noise. Next the power lose is increasing enough to almost no pulling power and a pretty bad engine shutter. I had to pull over and have her towed to the dealer.
I did have the Flashpaq on her and ran the DTC reader and no codes showed. No check engine lights nor any exhaust smoke. Gas was verified as being Shell Diesel ulsd 15ppm.
Any thoughts on what this may be? She has about 12,000 on her now.

 

Sorry to hear about that. Were you able to flash the truck back to stock before having it towed to the dealer? Maybe you will be the first to find out if the dealer can tell if it has been tuned. Hopefully it's nothing serious. I just turned over 1800 miles on mine today. Keep us posted on what they find.

 

I was able to get her to stosk w/o any problem. I have heard that there is a way for them to tell due to the computer.
One of the guys there, obviously this is w/o checking it and just a guess, said it sounded like a hung injector.
Thats what hydrolocked my 5.4 3v '05 150.

 

I have heard that those injectors are over $1000 each. It may not be true, but I hope that they don't try to screw you on your warranty by saying it was the tuner. I am curious to know if they can really tell it was tuned.

 

They are able to tell, since the introduction of the 6.0 i believe, and certainly the 6.4. There are two ways i believe - 1) The PCM records the last time that it was cleared or reflashed, and if this doesn't correspond to a dealer reflash, its a chip. 2) The PCM also records when the stock parameters I.E. fuel, EGTs, boost, ect. were exceeded.

Be honest with the dealer, and tell them you were running a chip on the truck. If the problem really was unrelated, which sounds the case, then if they are a decent dealer they should not give you too much trouble. Either way, they most likely will find you used, might be better if you were the one to come clean so they don't have to call you on it.

 

Personally... I am shying more away from the new diesels. As much as they are "cool" they are becoming useless in the mods department.

Well... next year I dunno what I'll be doing... but at least I'll have a lot more money instead of spending it all on college.

 

My 2007 6.0L did the same thing and it turned out to be the fuel filter.

 

Next year Diesel will probably be 6+Dollars a gallon, so keep your F-150!....

 

I am not worried about the programmer issue with them. I am more worried about the truck issue being caused by the programmer, if that makes any sense.
I guess we will find out soon enough.

 

Yeah, no kidding.

 

Did you ever find out what the problem was?

 

The goobers at the dealer (after it sat there for three days) pulled codes/called Ford/got a repair bulletin and are going at it.
They say it's either the whole bank of injectors, fuel pump or something else. It lost all power to the one side of the fuel rail, as I was told.
All they have now is a guess and Ford to steer them blindly down a dark road.
But on a lighter note, this is the third one recently they had in with the same issue.
Patiently waiting on my expensive dust collector to be fixed.

 

Dust collector? Air filter?

 

Thats not much of a lighter note....


He meant the TRUCK is a dust collector because all its doing is sitting in the shop.

 

Sheesh... that's not good... I hope it's not going to cause some kind of recall. (hint hint)...

Oh, sorry... I am a little buzzed... a friend came over with some bud and I've been drinking it all day like water... kinda buzzed out of my mind.

He left, and the only thing I've got is TV and this forum...
