My 1992 Lumina APV 3.1 stalls a lot when it idles. I believe it just needs an idle adjustment, but I don't know how to do this. Can you help?

I'm pretty sure your car has an "Idle Air Control" and this may be bad or the connectors to it could be corroded.

Check for a stuck open EGR valve,it will have to be removed to be checked.Or you have a large vacuum leak,either one will increase idle and fuel causing hot cat and high idle.
