    I am about to blow up my Jeep.
    Please HELP.
    I had to replace the torque converter, flywheel, starter, CSP, TPS, Idle air control.
    I can start my Jeep and it will purr like a kitten, shut it off and go to start her back up and she idles really rough.
    Does anyone have any ideas.

    That's a sign of an ignition coil issue.

    Can you give us a bit more info? Stuff like year, how long you leave the Jeep running, temps ETC. The first thing that comes to mind is fuel rail heat soak. Try letting it run turning it off and leaving the hood open while its off to let heat escape and see what that does.

    It will throw a code and then it will go away.

    It's potentially still saved. A cheap OBD2 bluetooth dongle is an excellent tool to keep around. I keep mine plugged in 24/7 and with the torque app can see what the engine and sensors are doing real time. It can scan and clear codes as well.
