Another Stupid Intermittent Problem

"Sometimes" when I first start up the jeep it idles real rough. I've popped the hood and looked for any visible problems but haven't located anything. It smoothes out if I just put it in drive and go on. I have noticed that it does it more frequently after it has been drove for a while, parked, and then started back up within 15-30 minutes. Any ideas?

How about starting with a tune-up? Cap rotar plugs and wires? The IAC can make a loopy idle at the start also.

Thanks for the tips! I've been considering doing the cap, rotor, wires, plugs, and O2 sensor. I figured even if it doesn't fix my problem it definetly won't hurt nothing. I am looking at the tune up kit from Summit for the ignition stuff, any suggestions for the O2 sensor? Any other ideas what might be causing this problem somtimes and not others?
