My 1989 Jeep Cherokee idles rough?
Recently I had all 6 of my fuel injectors replaced (not by a certified mechanic) and now my idle is really rough where as it was not before.
The person that replaced the injectors swears there is no connection but I have to wonder, Could there be?

Check for vacuum leaks, this has happened on my 1990 cherokee. It is possible that he knocked off a hose while working on the injectors. It is very easy to find the hoses with a diagram you can find online or in a repair manual. Also try treating the engine with Seafoam, you will feel a difference in engine response (it gets rid of buildup in the engine, I recommend it since your XJ is old). Good luck and I hope nothing else is wrong with it.
