Alright, i have been driving around for a while with a P0134 code now and im tired of seeing that SES light on. I do have headers on my car, hot-shot, and i did buy an o2 simulator. Its working fine and i installed it right but the light wont go away. Just an FYI i did replace Bank 1 sensor 2 and bank 2 sensor 2 because i broke them by mistake trying to take them off my oem parts. dont ask how lol. One thing i have noticed is that the code seems to be co,img from bank 1 sensor 1. Do i need to replace that sensor?
