Sounds a lot like a failing fuel pump relay. I have records for my car showing it being replaced about 5 years ago for the same issue. I replaced my fuel pumps last year as they were quite noisy and pulling higher amps, which can destroy the relay. May be the same issue on your car...

I re-installed that pinched vac tube and my idle was more "under control."
In park, it sits about 850-950 RPM, probably a bit high....
In drive, it sits about 600-650 RPM.
I think it might be running on the rich side, duty cycle reported about 38-43%.
