Icon5 SLight bucking regular speeds

My well maintained 98 3.0 5spd started bucking at normal highway/ 4lane speeds 45-70ish. It almost act like your in to high of a gear, but this is something new and thats not it. has anyone had this problem? What did you do to correct it? It seems to be getting worse

"bucking".....you mean is kinda bounces...vibrates?

My guess....wheel weight popped off, driveshaft weight popped off. Possible carcass going out on a tire causing it to become out of round.

Im sorry, its not a tire issue, its from the motor, its sort of like your lightly tapping the brake with your left foot while driving. It doesnt do it under hard accel, just at driving speeds,

Yes, it just came on and I had the code read, it was DPFE sensor fail or DPFE low voltage. I never heard of that part?
