I have a 99 xj with a stroker that I just put an ax15 in from a 97 xj. When I'm slowing down it starts missing and does, will start back up right away. Now I still have the auto ecu in it, but have the whole donor 97 do I just swap the ecu and unplug the tcu, or do I have to swap the entire harness in the engine bay.

The auto pcm doesnt have the same fuel decel programming that the manual pcm does so you do need a manual pcm.
