uhhhhhh ... the thing i always called an 'idle stabilizer' is a little black
box over behind the right rear tailight (along with a bunch of relays). that
thing that is supposed to buzz and humm is, i think, an idle-something-else-
valve.

>buzzing and can feel no vibration from the valve.  The electrical

the control unit is (Surprise!) under the rear seat, on the driver's side ...
it's behind a metal shield (so your junk doesn't mash it). now, that's the
MAIN control unit.

yeah, but take off the tail light anyway, and look around in there with a
flashlight. in my 1986 model there was (and is, on my 88 model) a little
plugboard in there, with some little black modules plugged into it. hard as
hell to unplug them, too.

well, i never did get mine to do what i thought the book was saying. so i
moved on to other things. finally just started replacing parts ... and when
i replaced the coolant temp sensor (is he gonna start THAT again!?), the idle
got amazingly better. so at that point, i stopped replacing parts. :)
