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

Iíve never been a fan of just replacing to replace.

If itís not causing an issue, IMO donít touch it

He said earlier Bank 2,

You said you were gonna replace all,

He said heís not a fan of replacing just to replace, basically just replace the sensor thatís giving you the problem

I guess I just figured if the bank 2 sensors went bad maybe the bank 1s will soon and if Iím there to replace 2 Iíd might as well replace all 4

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

"Sorry Iím a little confused what hardware / sensor issue do you think is causing this"

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
