New MAF questions

I've had really bad hunting at idle (cold and warm), and have been chasing it for some time now (1128 and 1130 showing). New MAF recently. Checked for vacuum leaks as well, but never considered the O2 sensors. Could these be culprit for bad idling conditions?

It is extremely rare for 02 sensors in both banks to fail simultaneously "1128 and 1130"
Failed MAF or vacuum leaks cause about 90% of these codes. A failed O2 sensor is usually revealed by "aging O2 sensor" codes. (P2096)
