My AF is definitely not consistent at idle. It varies between between 15-17 as you can see in the video at all times.

When the car is warming up however the AFs are good, cold startup is in the 13s as described.

I will check for vacuum leaks.

Will a leaking BOV cause this? I am going to attempt to switch over to a BPV and see what happens.
