2013 335xi stalling/ rough idle on cold start

So the last week my car has been having a rough idle to the point it stalls out I have no ghost codes or cels popping up but once the car is warm it seems fine and runs fine once warm has this happened to anyone els and if so if you could point me in the right direction that would be great

It had recently warmed up and it’s seems to have gotten and after I ran some injector clearer in it it seemed to help but it still seems to have a rougher idle still but doesn’t stall it’s self out

If you are talking about the BMS "hot air intake" that is plastic and has the bend near the MAF, that is one of the most problematic ones. Trying putting stock intake back on and see if it helps
