I have a '96 pathfinder with 116k miles on it . when I am doing about 60+mph it feels like I have the cruise control on and I am going up up . The truck speedy drops slightly then picks up again .


What could this be? How Can I fix it ?

Sounds like you need to have it hooked to a diagnostic machine, which should tell you what it is. Could be computer chip or something with the fuel injection.
