Have you also pulled out the cam sensor drive and checked it as well?

There are numerous XJ threads about persistent CEL or driveability problems that were finally solved by using genuine Jeep sensors.
Cheap parts are cheap for a reason.
This may or may not be helpful....but the only time my 2000 XJ has backfired through the intake it was the coil pack. It took me a long time to figure it out, as it intermittently threw a misfire code and the resistance on the coil pack was within specs. Just throwing it out there....
Do you have anyway to take video of it and upload it to youtube? Also how badly is the connector hosed, maybe you can halfway wire it in just to test?
Had this problem on my '96 4.0 and it turned out to be a worn out distributor. Pull the cap off and see if the shaft has ANY play in it, if so replace entire distributor to correct the problem.
Good luck..
Thank You for your input. That does help as it gives me another direction to look at.
I am kind of in the same boat though, as no codes are popping and as you stated the coils are testing as correct. But again, I work in a motorcycle shop and have seen first hand coils that test out fine on the bikes and still be confirmed as being problematic.
Looking at some used ones at the moment, maybe I can find one cheap enough to throw on as another test.
Did you ever test the fuel pressure? If it is low it will go extreme lean and cause what you are experiencing.
Also make sure the pins are tight on the coil pack plug and the cmp sensor, take a dental pick and tighten the plugs.
Also some newer jeep coil pack connectors are wired different, make sure your plug faces the same way as your old plug.
You will also need to set the cam crank correlation with a scan tool that shows that feature, i use a DRBII.
The pc sets the ignition timing but the cam sensor sets your injector timing
