Review on Forester Impreza Outback Tribeca Crosstrek by Emili Hudson

The O2 sensor showed "calibrating" for a while. But I ran the charcoal cleaner along with the gasoline. Then the calibration was finally erased. No, O2 code error in my ECU, now. I'm not sure if there is a quick way to recalibrate the ECU. I'm just glad I avoided changing the catalytic converter as this is an 80,000 mile car and shouldn't have any problems with the catalytic converter. I did this on a 2015 Subaru Impreza.
