The CEL hasn't come in because the ECU is still learning sensor input variances between the ideal sensor and your used sensors. Once it determines that one or more sensors fall outside the normal adaptation limits or other mechanical issue exists that prevents the adaptation values from correcting for, it will attempt to adjust trims to normalize operation. That will fail and you will see the CEL.

Ok. That does makes sense. Although I did replace the bank 2 pre and post cat oxygen sensors with brand new OEM parts and then fixed the PCV leak and never reset. I will drive it all weekend and report back.
