Stumbling Idle

Greetings to all from Louisville. I am a new member and am the proud owner of a 1999 XJ 4.0 It has 103K miles with Spicer Track Lock in rear Dana 44. I have owned the Jeep since 40K. I am experiencing a bad stumbling idle at start up. I have new plug wires/new Autolite plugs/new cam shaft position sensor/new IAC/new TPS and it still stumbles. I haven't checked the fuel pressure yet but have tried turning the key on repetitively to prime the pump and it still doesn't idle well. It acts like its hitting on 4 cylinders until it warms up. No codes on the computer. Please Help with suggestions Thanks
