Posted on bimmerforums, but no luck, so hopefully you guys can solve this.
I was driving along for ~an hour just fine and my car started to occasionally miss. Just one little skip. Then a while later all the sudden it starts bogging down and running like crap. I pull over, check fluids, start it back up, it runs fine, I hesitantly pull back into traffic. A couple minutes later it does it again. It idles perfectly and after idling for a minute it drives fine again. Does it again a couple minutes later, only now it won't rev past ~1500rpm. After sitting for a few mintues, it's fine again. The problem just keeps getting more frequent and severe, revving to less and less rpm when it happens. It wouldn't start for a few days. I replaced the fuel filter, pump, and FPR in that time. Then suddenly one day it starts, running crappy at first but smooths out and runs fine. I drove it around ~20min to make sure. A couple days later while driving it starts doing what it was doing before where it runs fine when I start it, but a couple minutes into driving it starts missing and bogging. After I let it idle a minute it'll run fine for a minute, then start to run like shit.
A couple days ago it began not even starting again. While it was running really crappy Right before it died, the CEL came on and I get code 1215 - airflow sensor. Don't know if this is related to my problem or maybe just because the car was really struggling to run.
Here's a vid of it trying to rev the first day it screwed up.
This is it barely starting after ~5 tries after the symptoms had gotten worse. It smooths out after running a minute.
