I can let my car warm up and it will go from 2k to about 1100rpms and stay there.

If I touch the throttle a little it will idle at about 1800rpms and stay there.

and if i drive it for about 5 minutes after i let it warm up it will idle at about 1800 and drop to about 1k then back to 1800rpms

So what could it be?

b18 is in my crx
