have actually had this problem a few times before when it was VERY cold out but I would not call it bucking.. It felt more like a slipping clutch or something along those lines.. Cap/Rotor/Plugs/Wires all replaced and the throttle body was cleaned and it only happened 1 time after that in the past few weeks. Today I left work, ran some errands and sat in the Jeep with it idling for about 20 minutes while I did some paperwork and what not. Left the parking lot and everything seemed fine. I got a few miles down the road and went to shift into third gear and the Jeep started bucking and popping.. I did not try to force it in third gear as I was at the bottom of a hill getting ready to go out so I let it slow a bit, dropped into second gear.. back up through third at partial to wide open throttle and no bucking. It did not do it anymore for the rest of the 20+ mile ride home.
A friend of mine is a Jeep tech at a local dealership and brought home the giant black computer thing for plugging into the OBD2 and scanning codes / adjusting stuff (sorry I can't remember the name) after we did the tune up and there were no codes and he went through every possible menu he could and came to the conclusion that the Jeep was running perfectly. No CEL or anything. Where should I start? This is my DD so I really can't have it go off the road and I don't want it to leave me stranded.. Ideas?
Its a 96 XJ with a motor from a 98. 6 inches of lift, 33's.. stock gears.. No motor mods other then a homemade intake that has been on there for for a long time. I have no temp gauge as of right now because the new head/motor does not connect to the old gauges.. New sender is on its way to put somewhere so I can have a temp gauge back.. Motor idles fine and normally runs great.. She is a bit groggy sometimes pulling hills but I can't blame it with 33's and stock gears right?
Also it has never stalled on me during any of its episodes.. Help me out@! Sorry for the long post!
