    what year is truck?
  5. Its a 2000. With 244000 miles on it and on sat I had to replace 2 coils to get rid of a miss. We now it is missing again so I am going to change all the plugs and hope that solves it. The last time that I chaged them was about at 100k so its do for them
  6. So that means I have to go to the stealer

    Being a 2000 you do not say if you bought new. If not you don't know who may have changed those plugs before you. Look in your truck manual that comes with it, if you still have one. Not sure about Ford but GM use to give at least 2 options for plugs.

    I would try a NAPA before a dealer. Heck K-Mart & Monkey Wards use to carry Motorcraft plugs.

    There are places other than the dealer that sell Motorcraft. You may also want to replace the coil/plug boots on the other 6 coils that are not new. Those are available from O'Rielly's or Carquest.
  10. I got it when it had 54000 on it.

    Stay with motorcraft plugs. You should be able to get them from Advance Auto or another part store. Check and make sure you dont have a leaking intake manifold or PCV hose which are common problems on those motors.
  12. Autolite lists a double platinum plug as oe equipment. Part# APP103. I would also replace the remaining coils as this is a common problem on those trucks. Part# in a Standard brand is FD503. You don't need to go to a dealer for these parts.
  13. Well I think that I am going to do plugs and change out the other 6 coils.

    Replace ALL of the coils. My 2000 5.4 was running like crap for a while. Found out 1 coil was cracked, which is why it ran especially bad in rainy weather. Week after the first one was replace I took it back to have 2 more coils replaced. A few days later it started running like crap again, so 2 more were replaced. Finally I had the last 3 replaced 2 weeks ago when I had new tires put on. Once 1 goes bad, the rest are sure to follow. Do them all at one time.
  15. Ok, got them done. Used NGK plugs cause that what i have the best of luck with them. The old ones where Motorcraft plat. Cleaned up all the coils, tested each one and they are ok, so we shall see how it works now. I can say that it has some balls now
