I Have been struggling to achieve all monitor's to be set as "ready"
I have all stage 3 Bolt-ons including a "cobb catted downpipe"
Why is my 02 sensor and 02 Rear Heat Sensor are not passing? My stage 3 protune has all emissions turned on, so I'm not bypassing anything. So I'm very concerned on what may be happening and I'm throwing a code P0420!
If anyone can help please help!!!
