There are a multitude of other possiblities. I mention the crankshaft position sensor because of the major recall.
Commander had another good suggestion in that you just had work done and now you have the problem. Could very well be just a vacuum line issue.
Other possibilities are camshaft position sensor, electronic module control.
When you find a mechanic, see if you can get a code out of the jeeps computer brain. A good mechanic will have the diagnostic capabilities to do such a thing.
A quick suggestion. You may want this post moved to the Central forum. Someone up that way may have a recommendation for you.
Good luck.

well make replacingg the computer the last thing you do in your troubleshooting.
and if you replace the crank sensor replace the cam sensor at the same time. it just makes sense to eliminate two bugs at the same time.
of course being a diesel you may get all of these issues if one(or more) of your glowplugs isnt ON. You ll get weak idle and black exhaust. This is a 4 cylinder or a 6? it is easy to imbalance a 4 cyl if just one cylinder is out of service.
And if you have the Jeep Cherokee Sport I believe this car was built in China, but its cool I thought it was way better than the Liberty that replaced it.
And since you mention replacing the alternator recently and getting these symptoms, you may have a defective alternator. If one of the rectifiers is bad, out of 3 I believe it has it will send an inconsistent current to the PCM and that can cause those kind of issues, as well as a bad wire harness to the alternator. Since I dont know the skill level of the guy you had turning a wrench on it, you might want to look it over for obvious junk he may have left undone or sloppy-fied.
