CIS low/rough idle solved!!
 

Thanks to everyone who helped me troubleshoot my low/rough and hunting idle. I finally decided to adjust my now-adjustable AAR again, and I must have hit on the perfect setting, because the idle is right where I want it. The car starts and idles between 1600 and 1900 rpms depending on the ambient temperature and then drops steadily over about a 10-minute period as the engine warms up. It settles on 1000 rpm just as the engine reaches operating temperature. It really makes the car more pleasurable to drive, not having to buck out of my driveway or around parking lots with an engine that sounds like it is about to stall.
