Engine accelerates sporadically on its own. Engine occasionally dies at stop lights. Must keep brake pedal firmly pushed at stop as engine will suddenly accelerate. I have already replaced the turbo. The dealer says it could be many different things wrong. The 2003-2007 diesels are notorious for bad turbo, fuel injectors and a head bolt problem that requires removing the cab. I purchased this truck new and it now has 39000 miles on it. This is a serious safety concern.

While driving my 2004 F150 and approaching a red light or turn my truck will intermittently shut off and need to be restarted. On several occasions I have had to put both hands on the wheel and crank (no power steering) or both feet on the brakes (no power brakes) because the truck turned off and I lost all power functions. It wouldn't have been as big of a deal if the dealer in my area hadn't told me this was "normal" for F150S and sent me on my way. Since that dealer I have dealt with 2 others in my area who say its normal and to just drive my truck until it fixes itself. I wasn't aware that Ford made self diagnosing/fixing vehicles. In either case I am extremely upset that this problem is for some reason not considered a problem and that there is no current fix for this issue. I no longer feel safe in my truck and have resorted to driving my parents vehicles until I can rid myself of this death trap. On another note I have also had the vehicle flash dash board lights at me after going over small bumps and then shutting off 1/4 of a mile later. When this problem was brought up the dealer said it was impossible (it's happened twice) and that I had to be imagining it.
