Broke out the two new OEM MAF's and two of the five new OEM IAC valves. Set MAF's to 380, a wee bit richer than the 383 and got not MAF plugs to avoid water intrusion. Install new IAC's.All done nice and pretty. Mu Ferrari mechanics mat for gratuitous effect.

New MAF's and IAC's smoothed the cold idle, which is odd as the car is open loop when cold and runs from a fixed map. Maybe the IAC's were a bigger factor but my old ones were very clean and looked shiny and new inside. Still they were 30 years in the car so maybe that did it. Consider rebuilding MAF's as a maintenance item. https://fuelinjectioncorp.com/ Just a thought.
