Eglin AFB? I live in Navarre and work in Crestview! Anyways, any time you pull the battery on a Ford, you have to drive for about 10 miles to get the computer's adaptive memeory to "relearn" the fuel and spark curves. If this returns or acts up again after driving for the 10 miles, could be something more to this. Is the check engine light on? If so, get the codes pulled out of it. If you do not have a scanner, stop in at AutZone or Discount Auto, and they will pull the codes for you.
