I have a 97 f150 with the 5.4. On the underside of the hood there is a Ford sticker stating it was reflashed in 99 prior to me bying it. The sticker says: module#F7PF-12A650-ADA. Is anyone familiar with this reflash and why it might have been done. Just curious.

 

Probably some sort of a recall.. have no idea why. There is a site to go to to check to see what recalls were performed on certain vehicle types....not specific vehicles just in general. But i dont know the site
maybe someone else will know if u really wanna find out.
