When the throttle is whacked open, AFR goes lean momentarily, not rich.

Throttle hang used to be endemic in the late-70s and the '80s until car makers got the necessary hardware to make EFI work right. That doesn't mean tour G is acting correctly, though.

Yea that's where I read about it but the most recent example was with a 2012 Yaris so I thought maybe it could be the issue being described.

I just Unplugged the battery (installed my grounding kit at the same time), cleaned my throttle bodies and after hooking everything back up I did the pedal position and throttle re-learn procedure.


Starts at :45s mark

My hope is, my doing this you will see the throttle RPMS react normally as his does (4:55 mark) vs the hang you experiencing.
