Turbo/boost failure 2008 F250
One of the turbo's was squealing at about 99k, the dealer said they replace the turbo, now I have the following intermittent problem. The turbo/boost fails and the truck has no acceleration. You can see the boost gauge is at zero and the accelerator is mashed to the floor, I could be cruising at 80 on the freeway and the back off for a second then try and pass a car and the boost dies, nothing. I pump the accelerator, put it neutral and rev the engine repeatedly until the boost comes back. This happens in a thousand different scenarios, to many to explain. The dealer had engineers look at the truck and they said there was an excess of carbon build up in the turbo's, I don’t know what they did but they cleaned it up and it went away for about 10k miles, now it’s back and much worse. The truck now has 129k miles on it and I’m at a loss, obviously it’s out of warranty. Any ideas anyone?

loss boost and power
I have a 2008 F-350 with kind of the same problem, if I'm driving at about a 100 km and floor the truck to pass a car i have no power about a 1/4 of boost, then if you let off and ease in to the peddle the boost comes up but slowly. if you pull over and shut the truck off and start it back up the power is back and works find till u drive at a 100 or slower for 10 or 15 min. some times if you hold the peddle to the floor till it govern out the power will come back. i have had it in to ford a few time and they can't find anything wrong with it.
