P2098 Post Catalyst Fuel Trim System Too Lean

This came on eighty miles after my oil change. Not sure that it's related but....

ODB2 lists the code as permanent and confirmed. I don't see this listed anywhere else on the forum.

What do you mean by that? It idles smoothly. And after warmup it settles at .5

On the other hand why does O2 Sensor 1 read 0.0?
