Truck Hesitates when under Load
Hey guys, new to the forum. I have an 06 F350 KR with 83K on the odometer. No mods or programmer, all the factory services have been performed. Took the truck in to the Dealer a month ago and was having issues with a leak, and some Hesitation that had developed.
The Hesitation is mainly when I either get into the throttle from a start, and its seems to stutter. It also happens when I am on the Highway 70-75 Mph, and I am approaching a hill, the truck again stutters, and hesitates.
I told the dealer at the time, it seems to be "hunting" or starving for fuel.
So they found the Fuel Pressure Regulator was leaking fuel, so they replaced the gasket (O-Ring).
Got the truck back seemed ok, yet then another leak - this time the Fuel Filter Housing.
Back to the Dealer and told them the hesitation was back. They fixed the Fuel Filter, and stated they saw a code for low fuel level. I asked did they mean Fuel Pressure, and they said no, Fuel Level in the Tank. At the time I also told them of the Ford Blue Spring upgrade, yet that when in one ear and out the other.
Well, Truck is doing it again, and I do not have a heavy foot. Its just very annoying to be driving along and it is probably starving for fuel.
I used to work on Diesels in the Army mainly 2 stoke Detroit Diesels and to me it seems like the blue spring upgrade is worth a shot.
I just want to see if anyone has had similar issues, and can either confirm or deny that the blue spring mod is a fix, or I may have another issue at hand.
That being said, I will do the work myself this time.
Any help is appreciated.
