For fuel injected engines, my manual mentions an "A/C [as in
air conditioning] idle control solenoid valve." I don't see
anything similar for carbureted engines.

For the carbureted 87, by way of what to put one's hands on
during the two idle adjusment procedures and when using the
troubleshooting chart, my manual lists:
(1) a "throttle stop screw" (there's a drawing of where this
is);
(2) a "fast idle adjusting screw" (also shows a drawing of
where this is);
(3) a "stuck air bypass valve" (troubleshooting section).
(4) a "stuck open throttle valve" [So try cleaning the
carburetor?]

Again, I'm not a carburetor person. I'm just copying from
the manual here, trying to learn more. I defer to your hands
on and book experience, Mike, of course.

Okay,
I located two vacuum leaks on the back of the carb, put new hoses on and
readjusted the idle screw. That seems to have fixed the problem. I still
need to change the O2 sensor.

I lubricated all the linkages and springs.

Once I drive to work and then back home I will see if I need to tweak it
anymore.

I do appreciate the help and web sites.
