We're at 60F lately and still does when coolant temps are cold.
So definitely not the IL.
New coils (Bosch) and new plugs (Iridium IX)
All new gaskets and seals when VSS was done including 8 new vanos seals.
Can't figure it out.... I've switched around the coils to see if it follows but it didn't.
What else?!?!
Not losing any coolant or oil either.

I changed the mass airflow meter on my 323i and it fixed the random misfiring when starting up from time to time.
Cant promise it will fix yours but it flat fix the 323i's issues with it.
The meter eventually got bad enough it either popped a code I tracked to it or some other symptom popped up. I can't remember. I was surprised when it straightened out the missing when starting it sometimes. Since it had done it for years before I changed it.
