Difference between 97 and 98 XJ distributor?
Anyone know what the difference is between the 97 and 98 distributor? I did a 5 speed swap on my 97 with 98 parts and the jeep kind lurches around during medium throttle. At times it will backfire out the intake, mainly when cold.
I can see that the part numbers are different between the 2 but both years use the same cam, cap and rotor. Maybe the shaft puts is a little different than the 97 position wise and the 98 PCM is set up for this? If so I should be able to put my 97 auto PCM back in and test drive it to see if this is correct and if so just swap the distributors?
Fwiw I did the complete swap, wire harness' and all... Just left the 97 distributor in.

The two distributors are mechnically the same but the switch plates (Cam Sensors) are different, so you should put a '98 switch plate in the '97 distributor.

97 vs 98 ZJ
I have a similar situation here, I have a 98 ZJ and recently had to replace the engine, I got a used 97 engine and after being installed had seemed to work fine for awhile however after awhile it started sounding a bit rough and when starting on a cold engine it would shake the whole engine. Then one day when accelerating from stop it backfired and sputtered, would not restart. Took it to a shop and they said the distributor was all torn up and needed to be replaced. After replacing it they still could not get it running properly and suggested I take it to the dealership, which I did. They replaced the CPS and distributor plate. I noticed all parts that were installed were for the 98 Jeep yet I now have a 97 engine. Could this be the cause of the issue I now have and if so what would I need to do to remedy the situation to get the Jeep running again?
