Triggered safety 2- afr lean

Bank 2 goes out of whack- based on log- looks like a hardware / sensor issue.

Could try an adaptation reset first, but Iíd replace

Do you recommend going with the oem o2 sensors or maybe upgrading to NTK or adv sensors

I get what you are saying..... but you did say you were confused on what sensor he was talking about.

If it makes you feel better then change all of them
