I'm having the same problem on my YJ on cold mornings. I haven't found the solution yet though. on a cold morning mine idles at 5600 rpms but in the afternoon it gets up to 1100 rpms and the missing stops.

Check your intake manifold gasket where it mounts to the head for leaks, you can use a can starter spray to do this,it spray around the intake and head area and if you here a change in the idle you are sucking air from other than the intake where it should be, be sure you don't have any spark jump from your distributor or wires if you do it will scare the hell out of you if the spray flashes.[addsig]
