My 98 XJ 4.0 idles rough, but only sometimes. Runs great 90% of the time. Sometimes when it starts up it will miss real bad and stall, after I start it again its fine. Sometimes when its just idling it will drop to about 500 rpm and start missing. It seems like the computer is trying to fix it cause it will rev up but then drop back down. I haven't had any problems driving usually on start up or just sitting and idling.
