I have a 1999 Jeep Cherokee that my office uses on a daily basis. The vehicle shutters while at an idle, almost like a miss. If you give it some fuel it will stop doing it. However, it seems to only do it after it has been running long enough to be warm. We have changed the plugs, wires, cap, and rotor button. Do you guys have any ideas?

Thanks for any help you can give me!!

Try an upper engine intake cleaning
And also a professional fuel injection cleaning at a shop:

I have seen some lazy injectors on these that I have had luck with cleaning them.
