Did you clean the shaft on the Idle Air Control motor? You might try
unplugging the IAC and see if it makes any difference. If not, that's
your problem. When I first got my MJ I had idle problems that improved a
little with each fix until a new O2 sensor cleared the last bit of
roughness.

AH! just hit me - that sounds like what I got with a failing fuel pump - I
was losing pressure after it started - but even with added throttle mine
would die pretty quickly.

Re: Oil pressure problem fixed
 

You might want to describe carefully what parts you've busted, even if
just by location and what they appear to be connected to.

As for old or cold, I would think it would need to be really cold to be
that bad. Replace 'em.

Re: Oil pressure problem fixed
 

I looked at the check engine code, I got a 13 - MAP sensor.
Seem like that would do it? Or should I replace the MAP sensor, not
expecting it to fix the current problem?

I have to replace 'em, since I shattered 'em. I broke the CCV air
outtakes on both the XJ and YJ and a heater hose coupling (don't know
exactly what it's called, it's four hoses coming together with a small
vacuum).
The rubber on the YJ CCV piece was obviously dried out, so I'm not
surprised that broke when I tried to put it back in. The XJ CCV piece
snapped when I pulled on it not very hard.
The hose coupling shattered when I tried to move it out of the way so I
could get to either the #4 or 5 spark plug.
I didn't put much force on either of the XJ parts and they basically
shattered.
