My 97 Ford Expeditions Check engine light came on blinking while driving 75mph

you might want to get the computer reprogrammed and for the codes you pull, the dts codes are generic and they will or should have every code that has ever come up. after extensive research and reading 100's of forums from various companies I found that the "Hypertech Max" Programmer was just what I was looking for. few questions, where do you fuel ur suv??? what Octane do you use 85/87/93??? who does your oil changes???
