x308 1999 4.0 Non supercharged.... no error stall

Hi folks
Car seems good overall, but at start up & idle today it was sometimes uneven, thought it was about to stall, but came back to being ok, yet seemed a bit rough sometimes.
The last time this all occurred, it was stalling completely, and i got codes for the Upper O2 sensors
& i replaced them.
this time, really its only occurred today only , the stalling is much much less, I thought maybe the lower O2 sensors initially were the culprit, but i have no OBD2 error codes indicating anything is at fauit.
MAF sensor replace 3 years ago, cleaned a few months ago
Upper O2 sensors replaced, Bosch replacement.... but lowers not replaced yet
New fuel filter, fuel pressure regulator cleaned
Air trunking is New OEM a few years ago
Question is....apart from looking for air leaks (air trunking ie pretty new though), do i wait for
an OBD2 code to come for the possible Lower O2 sensor or just replace them? Or is their something else to consider
I dont want to be stranded with the car, would like to find the problem
