So i replaced the front o2 sensor on my car with a denso sensor.
I went to get my emissions tested but it wasnt ready.
they told me to do a drive cycle that they suggested which i did then went to test again and once again failed.
I called subaru dealership and they told me to do a different drive cycle and i also did one according to forums on here as well and after 300 miles the sensor is still "not ready"
I have now expired tabs and am not sure what i should do.. any suggestions??
