I just realized the N53 is direct injected... I would think it's not injector related given mine is port-injected.
And mine being a manual tranny in which I changed the oil 4 times in 40k miles, I doubt it's anything related to tranny.
Excellent to see more info about different attempts to solve this. I for one I'm still stumped...

Silly question, but have you done a smoke test to see if you have any vacuum leaks? Vacuum leaks can lead to bad idle etc.
I didn’t bother to read it all, but have you tried swapping MAF and clean your throttle body?
