Just changed O2 Sensor
I have been having Check Engine With CodenP0135 Heated Oxygen Sensor (HO2S) Heater Circuit Bank 1 Sensor 1-B
Changed the sensor this afternoon.
First drive around the block got Code P0172 Fuel Trim System Rich bank 1-B with very rough idle.
Reset codes and took it out on the highway and kinda blew it out. No codes now and idle back to normal.
Was PCM just getting used to O2 sensor working again? Or what. Thanks for any advice.
