P0133 and P0153 I did a search and came up with alot of ****, but nothing definite.
I got these codes about a month ago. The SES light came on right after I hit my car with a 50 shot dry of nitrous. I deleted the codes and the came back two days later. Last night I deleted them again and monitored with HPT, the 02's are a slow wave form when driving normal, not what they used to be like.
I have LT's that I put on with the cat-back over 1 year ago. About 2 weeks before this happened, I installed an SLP air-lid and ported TB. I also tuned the car, and honestly, it does run "fat," but that is only at WOT.
Car runs great, no driveability issues at all.
Here is what I was going to do. First check for any leaks, if that checks out ok, I think I'm going to just replace the sensors with OEM GM rear corvette sensors and re-monitor my 02's. If the concern is still present, I am just going to delete the codes to "No-error-reported."
Does this sound about right to you guys. Any other suggestions?

From what I read in the link below the corvette rear sensors actually run colder, which is opposite of why everyone feels the need to run them.
