And I do not have an answer to your question, but figured cleaning the MAFs would be an easy, cheap thing to check.
Gotcha. It definitely threw me off the one time it did it to me. I think I had given the throttle a little bit of a "punch" to get it in gear, and that hitting the brake and stopping the car stopped it. I'd be curious to know if others could replicate it by doing the same thing. I'd try it again myself (for science), but it's garaged up for the winter now.

I can't recall if there's been another time I actually started backing out during cold start. Both before and after that my practice has always been to give it ~30 seconds (or at minimum until the cold start ends) to start driving on a cold engine, anyways.

P.S. I'm enjoying reading through your 135i build thread
