Well, a simple IACV cleaning made some improvement, and definitely changed
things. Its generally holding normal idle better , seems to be slower than
before responding to shutting the main throttle from speed. It still will
occassionally stumble into a stall after extended low RPM idling at about
750 RPM, but a big improvement from what it was doing recently. At one
point after the cleaning, it hung up at 3K RPM with the main throttle shut
after an upshift. Didn't ever do that before. All I did was give a
uick soaking spray in both ports with some WD-40 and some starting ether
spray (couldn't find any carb cleaner in the garage, and there was a warning
sticker on the IAC with the caution that it should NOT be cleaned due to a
special finish on the internal throttle pate and stem assemby).
It didnt look that coked up, but there was a definite coating of carbon on
the stem and disc inside the body. May try giving it an extended soak in
some carb cleaner (being careful to keep it from seeping into the solenoid
stem) got nothing to lose by doing so - if that doesn't work I'll need to
spring 60 bucks at AutoZone for a replacment.

Also replaced the PCV and associated vacuum hose bits, and put hose clamps
on all associated joints - didn't make much difference though.
