Maybe is the afm. Had this problem twice. I clean the AFM with CRC contact cleaner (non oil based).

I have a spare AFM, just clean the AFM with CRC and let it dry for few hours, then swap out my car AFM. Keep the dirty AFM in the store.

Mine happen after engine fully warm up, and drove for minimal 20mins. Think the engine bay heat may have heat up the AFM making it go crazy. The car feel sluggish, and RPM may drop when you try to accelerate from standstill.

AAC dirty may cause idling problem too.
