Hay guys, i have this 5.2 orvis jeep and while driving over 40 mph and just slightly on the throttle it bucks, take foot off throttle and goes away. press a little harder and goea away. only happens on flat surface any speed over 40. if you come to an incline goes away. does not miss at idle or accleration. new o2 sensor, cat, plugs, wires, cap, rotor, fuel filtter, no engine codes, brand new trans. does with or without being in overdrive? anyone want to give this one a shot?:runaround::disappoin:eek7::screwy:
