When I bought my '88 with a 4.0L the throttle body was so gunked up
that I wound up taking it off the manifold and putting it in a
ultrasonic tank full of Carter's - for an hour.

You mention problems with overshoot with a fast on-off the throttle
move. That was the last step in my saga - took a couple of months to
get it running right. It took a new O2 sensor to get rid of the last
little bit of the stumble. Remember that the O2 is primarily
effective at idle and mine was apparently too tired to react fast
enough on that sudden throttle movement to idle. Hell, it only had
125k on the clock when I changed it - should last longer than that!
