It eventually went away as the mornings turned cool and then cold, and didn't come back this year when they got warm again. Very strange.

I'll also say my stock charge pipe just exploded a week ago and I'm in the middle of ordering a new one. With the charge pipe disconnected, my car starts but doesn't idle for long before completely conking out. Assuming too much air. In light of that issue, I had started to assume my issue last summer was maybe because the charge pipe connection was poor and was leaking air or something.
I found your videos and that is exactly how mine is acting I already have replaced the charge pipe a few months ago. What I find interesting is i never had a problem for the 2.5 years I have owned the car until just a few weeks ago. I would recommend doing what is outlined above even if your symptom resolved I have definitely noticed a big difference in how the car is running
