I have a 1994 f-250 with a 5.0. After it has been turned off for a few minutes it wants to rev high and die

Question

when it is restarted and placed in any gear. Also when i use the back tank it goes up with my speed and down when i stop.

Answer 1

HAd a 95 f-150 that had same problem i would check the throttle position sensor most likely your problem not very expensive to replace

although sometimes mine would barely run when i started it it felt like it was only running on 2 or 3 cylinders.  I would start with that should be located on top of engine underneath throttle body
