On the way out to Az in (2006 in oct.) we got 9.5-9.0mpg
We were getting 13.4-14.0mpg from 2002-2006 We took it to a Ford dealer and they said that they reprogramed the computer and that i should be getting better fuel milage. I did Not, I got 10.5-10.0mpg
on the way back to NY. in 2007 I was also told that their is No Chip that could be used that would help.
