So, coming back to this.
The symptoms came back about a month or two ago with the colder weather. It was really noticeable when putting the car into gear right after starting the engine.
Since I had the plenum off the other day, I changed out the fuel breather valve. I ordered one a year ago and never got around to changing it out. All symptoms of fluctuating idle are now gone.
