O2 weird situation
Hello, can someone please help me with a weird situation regarding an o2 sensor that is acting very strange
So, the story is this, about an year ago I bought a 986 from 99. Love the car but i had stored in the ecu an error: o2 ahead of cat bank 1 no signal. No check engine on the dash.
I proceeded to change the sensor with a brand new Bosch part. After installing the part i now get the error: 02 Sensor Ahead Of Cat. Conv., Cylinder (1-3) below limit value
No leaks on the exhaust, the check engine is off but i don t get it why the ecu shows this error, specially the o2 is new.
Could this be related to the fact that i have a Dansk Motorsport exhaust?
Thank you
