Idle issue

My '89 YJ, 4 cylinder has a rough idle as of late. When you crank it up, the RPM's bounce from about 500 - 1000. Is this normal? Sometimes, the idle goes so low that it almost stalls.

So far, I have changed plugs, wires, distributor cap, fuel filter and MAP. any other ideas?

This is my first YJ...used to have an '81 CJ5 I6. Now I have to get used to the 4 cylinder.

Thanks for any help you can provide.
