I have this problem where it would be like a stumble/bucking but this is the funny part my 88XJ would run horribly for the first 10-15 of driving wouldn't go if I hit the gas and it sounded like a 30 year old beat up V8 with crappy exhaust (usually on the way to work) and if I decide to hold it at around 2500-3000 RPM it would stumble then buck, usually bucking pretty hard, it's like something cut off the gas then in that same instant you get launched into the seat. After that it would run like a champ, tromp on it it would snap the speedo, plant you in the seat and sound like a built hotrod, like it used to and it would be fine ti'll it was turned off. When I start it up again same process again. The exhaust is new along with a new cat new wires, cap, plugs ect. Don't know what it could be.
