Idle Hunting

So at a stop the idle hunts from maybe 700-900rpm. Regular idle is around 710-720rpm
This just started tonight.
What are the prime suspects?
No codes present.

Throttle position sensor?
I had that a while back.
Eventually gets weirder and weirder until it throws a code.
OH, and it might go into limp mode at start.

Eventually it will throw a code, but both of the above is easy to check and/or measure.
Maybe a vacuum leak?

Quick update.
So the upstream O2 sensors are toast and took out my cats.
Time for metallic cats I guess
