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,

 

Bump,

 

Sounds like you have a miss.Any chek engine lights?

 

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?

 

3.0tdci ranger, My Cranks sensor on bellhousing was damaged after clutch flywheel change, caused jerking and rough running engine at low speeds, very intermittend

 

 

 

THAT is one of the issues I see on all forums.
Posts just STOPS. No solution or the O.P. never comes back and reports.
EG: .. "I dont have access to a impact. I think Im going to try putting a jack uder it with the press and jack it slowly in there. I will let yall know if this works."
Did the O.P. die under a fallen jack?
