P015A- O2 Sensor Delayed Response - Rich to Lean

[14SWTahoe]

Any one else have this code? Mods are in my sig.

I have an email into Justin at BBP but wanted to see if any one has had this issue and possible resolution.

Just came on this morning, I cleared it and will see if it comes back.

Did you ever figure out what the issue was causing this code? I have the P015b code showing and now the other sides O2 sensor is throwing a code too.
