Hi, finding a problem like this,without throwing parts in can take quite a bit of diagnostic time,even with all the proper testing tools. One possibility is a valve lifter holding a valves partially open.I am sending you a link to a video,this is a case study of a problem that sounds similar to yours,clink on the link,then watch and listen to what was done and what finally solved the problem. I believe you will find it interesting,and may help you diagnose your Jeeps miss.
I agree with the possiblity, however, that would suggest that this happens everytime I cold start. That is not the case. I will cold start lets say 20 times and it will not happen, but on the 21 it will. Then as soon as I shut the car off and restart the problem self resolves. It is intermittent... and kinda like a fuel pressure issue. what I can not understand is the relation to the hard cold start, the subsequent missfire, and then the self resolve on the immediate shut down and restart. It is almost as if the computer is at play in some way.
