Ok, so my uncle has an 05 f350, that has been like a redheaded step child, so far within the past 30,000 miles this truck has had all new injectors, injector pump, fuel filters done every 15k since new, egr, and glow plugs. Well now we have a new problem, i was driving it earlier and it started to buck like crazy, then it just stopped. When i left from a light, it started to do the same thing, so i tried to ease my way into the pedal to try and find a happy spot, none. All of this and its still making boost, i'm lost, so is he, the truck isn't under warranty anymore, so any help would be great. Oh and the truck is bone stock with about 135k on it.

 

tranny maybe is it an auto

 

yeah it is auto, trans seems to be ok, it started puffing brown smoke, it wasnt black, and it wasn't blue, i was think like burning oil maybe, do those have a high pressure oil pump

 

yeah its possible that the hpop might be going bad

 

how expensive is that? anyone delt with it yet

 

maybe an FICM? mine started doing something similar. $1000 by the time all said and done with parts and labour. Mind you I'm in Canada, don't know what the pricing is like in the US.

 

well still haven't heard back on it yet, its at a ford dealer, this is going to be expensive

 

well, thanks everyone for the input, finally got the truck back today, $1900 later we got her all fixed up. Took 3 new injectors, and an FICM!!!!

 

Next time, there is a procedure on testing and fixing the FICM yourself, for nothing more than a little of your time and some soldering.

I had a dealer try telling me an 04 6.0 needed 4 new injectors, shortly after we had gotten a FICM code. The code was cleared and they kept getting injector codes. Injectors 2,4,6, and 8. It didn't make sense to me that all 4 injectors on one bank went bad at once, so we replaced the FICM and problem solved.
