Lose of power
2005 Ford x V10. After driving for a couple hours on the freeway when I try accelerate quickly it down shifts and revs up only to bog down. I can put the pedal al the way to the floor and it will still lose speed. If I keep the rpms low it does fine. I have done new plugs and a fuel filter and replaced the coil on the #8 cylinder as I was told that one was missing when it was hooked up on the computer at the dealer. Any ideas would be greatly appreciated. Thanks

sounds like loss of fuel pressure, or a clogged cat.
Check the fuel rail on the passenger side for something that looks like a tire valve also known as a Schrader valve. If you have one, hook up a fuel pressure gauge, pin it under your wiper arm, and take it for a drive. Under load, the fuel pressure shoudl never drop below 38-40 lbs.
If you don't have a valve on the fuel rail, and the computer has a fuel pressure sensor (not sure if the 2005 X V10 does) then the Android app Torque and a cheap OBD-II bluetooth adapter off Amazon should be able to read the fuel pressure.
