High/Hanging Idle

Check throttle plate gaps maybe, 0 IAC counts is usually for a reason. And are those really original injectors?

I went back out to the shop and checked the throttle plates earlier and they are closed. I also pressed on them with the car running to see if they were binding and they are not.

A thick folder over the air horn still fails to stall the engine, so air is coming in from somewhere. When covered, engine rpm does drop to where it should be. I?m running out of places to look so the primary injector o-rings are looking like the next point of interest. I have pulled a vacuum on every line Ive had access to this far and they hold. I repaired two lines and they successfully hold vacuum now.

According to the prior owner, who owned the car for 22 years, only two of the injectors have been replaced. He says he ran nothing but ethanol free fuel which may have something to do with their lifespan. I?m leaning towards pulling the plenum again and removing the fuel rail to insect/replace whatever I find.
