85 5.0 bucking
as the title states, my 85 ef one fitty, e ef eye has been bucking a little going down the road. Idles good, when you wrap on it, it takes off nice. But just a weird bucking, i guess more of a speed surge under light throttle.
plus my gas mileage has taken a massive hit as of late too, not sure if thats related or not.
no codes.

Start checking all the simple things; plug condition, fuel pressure, vacuum, spark. I had two cars that had surges under light throttle steady cruise. Both were caused by vacuum leaks, and made the gas mileage drop. It may or may not be your problem.
