My 1990 idles at about 850 and with the ac on 1100
The idle is not adjustable. It is computer controlled with a idle air control motor that is on the back of the throttle body. If your idle speed is incorrect you either have a computer that has "forgot" how to idle or a sensor issue. You need to have it checked for codes, if no codes you need to reset the computer's memory. You can reset the memory by unhooking the battery for 5 minutes. If it now idles properly you should have the battery tested, a weak battery can cause the computer to "forget" how to idle.
Auto Zone will read your computer codes for FREE. Have them reset your computer too. And then go from there.

Adjust the idle screw.
My 91 rx7 idles at 1000-1200, which i believe is the norm.
check your timing & up your idle a little
I also wish someone would answer this question as my 1997 Ford contour does the same thing. It shakes and vibrates very bad when it idles and it idles really low. They set the idle up to make it so it wouldn't die so now when I start it it revs up really bad then it idles down then it idles down to low and shakes I also wish someone would answer this question as my 1997 Ford contour does the same thing.

bad tps
They are not supposed to be reset because they are factory set to comply with emission laws. yes but where is it located
If you have a carburetor, there is a crew on the driver side behind the throttle cable it usually has a spring on it if you turn it to the right it idles up left it idles down If its a fuel injected motor idle is handled by the computer. There usually is a "base idle speed" around 800-1000 RPM. This normally doesn't need to be adjusted. Have a look for carbon build up on the butterfly as well, this will influence idle too.
idle control valve faulty or needs cleaning
my 1988 4ws Honda prelude idles low at 600 rpm
