Remove interior driver's door panel, should be on "brain"
It should be preset from the factory
The factory code can never be erased. Even when you program another code in, it will not eliminate the old code. It will just exist alongside the old one, so that both codes will work.-----------------------------------------The above person is haft correct regarding the factory code can never be erased.You can erase the old codes you had before and program a new codes in as long as it's not the factory code. Even the factory code can be change by the dealer only.Below are two links to the ford owner's manual.

buy ngk platnium. gap is factory preset.
it is preset at the factory and the computer adjustes it as necesary. No adjustment possible on distributorless ignitions.
Enter the code with the preset buttons on the radio.
The adjustments are preset at the factory. If the door is sagging it may need new hinge pins and bushings. IF you have changed doors and the hinge pins and bushings are good the adjustments are on the door post behind the dash or the kick panel on the bottom. The hinges are commonly tack welded in place and the welds have to be broken. It is a royal pain in the neck to get to the adjustments. If you have a factory service manual or a Chilton or Haynes manual you will find better help there. GOOD LUCK
On the factory i don't really know.
