I've checked these things before, but I can do it again. No harm in
that and it's been a few weeks.

I think I'll pull the AAR and see if the screw is still there. If it
fell out, at least I have an external oil filter....

No clicking or any other funny noises.

Yes, this problem definitely only happens at idle. Zero jerkiness or
anything else under any other driving conditions. That's partly why I
didn't post about it for a while, but now it's suddenly gotten more
acute and I haven't enjoyed stalling in traffic.
