New Engine Codes--no 'check engine' light though...

[cngizbleevng]

Don't know what to make of this.

Recently, after running my car at 5500 rpms for a few minutes, and getting codes related to bank 1 with a rough running engine, I replaced the O2 sensor and the car was running well. I thought my problems were fixed, but messing around with INPA this evening I got the following codes, even though the 'check engine' light hadn't come on. Any thoughts?

You had cleared the errors from before?

See how it says "Error not available", those are historical stored errors. It would say "error present and current" if still valid.

Hmmm, well I thought I had cleared them. I did clear them tonight after taking those readings. I'll recheck in a few days and see if they reappear.

I would think both O2 sensors are in need of replacement.

Additionally, I would expect a period or re-adaptation that has to occur.
