Idle problem remains a odd frustrating headache after much work.

I had posted a problem about this before.... and proclaimed my victory after a tune up........ then back to the same issues the next day.
SO, i have replaced the idle position sensor. Cleaned the throttle body but not off the intake clean, but cleaned it.
also the tune up mentioned above.
and no codes, computer isn't throwing back any codes not sure if computer keeps track of this.
When first started for the day,it's ok..... idles a bit high and settles down once warmed up a bit...... so if i keep driving it around and not turn it off it seems to be ok for the most part..... sometimes once it gets up to normal operating temp. it will idle a bit low.
SO i turn it off and start it right back up last week at mechanic's shop and it works just fine of course.
most of the time if i go out and get back in it to go home etc. it either won't start without pushing on the gas, reving it a bit, or kinda driving with both feet.
When this thing acts up you can put it in drive and it idles so low it will learch forward bit at a time.
So if anyone has any ideas, let me know....... I would test for a vacuum leak but don't know how to do that.
Could it be a intermittent problem with the crank position sensor? I had that go bad before but usually the jeep just won't start or runs messed up.
I also can't understand the odd sometimes working behavior....... and no consistent problem to find a solution.
this isn't a 1986 jeep with a carb or something, so not sure whats going on, this sort of can't figure it out stuff should be behind us with OBDII etc? i dont intend to go on any sort of rant but this has been a problem for a long enough now.
ALMOST FORGOT: 2000 jeep cherokee 4.0L ( with the coil packs not regular ignition plug wires etc) ..... its a limited XJ trim, that shouldn't matter but thats what it is.
