FWIW, I am the third owner of this Jeep. The original owner said they used to run on the interstate with it all the time and it never ran like that. Now that could be a miscommunication somewhere obviously. I guess that is what started the whole question. Somebody said it was fine at one time, but its not now....
Ill check gears. I have a MJ D44 that I'm going to swap into this eventually with 3.55s.
