I just picked up a 96 XJ 4.0 Auto. It has a wierd hesitation problem every once and a while. Do 96 cherokees have mass airflow sensors?
 
No, it is a Manifold Air Pressure system.
 
Any number of things.

Test your TPS, check the fuel pressure, clean the IAC and throttle body.

Post back results.
 
I get some hesitation whenever I start it for the first time, but will go away for a while if I do some Fuel injector cleaner. Probly because I use cheap gas ....
