Did a little screwing around today. I had bought an AFM from a user on here and ever since it was put in the car I had a terrible idle and rpm dip off idle. So I hooked up a scan tool and watched the O2 sensor voltage.
Sure enough the car is scewed rich.

Did a little fondling of the AFM, made sure it had no dead spots.
Then played with the spring setting to get more air during idle and came up with this. It's slightly better, a little more scewed towards 450 millivolts.

And now there's no bog off idle, at operating temperature at least.
There's only so much you can do with these AFM's and this car has always ran rich. Someday I'll pay the car the respect and rebuild the motor with a snail attached to it.
To end the day I finished splitting the wheels so I can go get a quote on sandblasting and powder coating this week.

If there's time tomorrow I'll get started on sanding as many square feet of the car as I can in the day. Progress, progress, progress.
