Well I think I found a way to test it. I set forscan to read IAC duty cycle and RPM and then setup controls to change the duty cycle.

RPM follows IAC duty cycle changes except for anything below 20%. 20% and below stays the same RPM.
I took it for a drive and before I did that I cleared PCM adaptations. No misfires list in forscan and also no misfires counted in Mode $06. Idle is still kinda garbage at some points. Give it a slight bit of gas (like 1500 rpms) and I can fill it mis.
