The gate never really shuts all the way on my AAV, it leave about 15% open at the end, this was after I had it out and hooked to a battery.

I'm looking at just about everything to help cure an inconsistent idle problem that I have. I have had three CO adjustments now, most recently because I did a valve job, and I still can't get the sucker to idle correctly.

First start the idle is low, and then it gets better. Then after driving for a while it sits around 1500RPM and never drops down. I had my wrench check the hot and cold pressures and they were supposedly correct.

All of the o-rings and one injector were replaced in this effort, all new intake runner boots, and new intake gaskets as well. So I am going part by part to figure out what is going on.

I do notice that on my 80 there are two large diaphragms on the passenger side, the very top diaphragm is disconnected, and if I apply vacuum to it the idle jumps to 3000K and stays there. (It was unplugged when I bought the car.) At the time of purchase it ran great no issues, even passed smog with flying colors, and now this issue.

I am down to a leaky injector at this point since everything else has been checked or replaced. Any ideas?
