alright so i went to vato zone and checker and had thm both scan my obdii cuz i dont trust auto zone. but autozone pulled a P0141 HO2S Heater Performance Bank 1 Sensor 2, and i do belive checker pulled a P0144 HO2S Circuit High Voltage Bank 1 Sensor 3. should i go ahead and pay the 140 dollars for both parts to fix them or do i try to clear them and see if they come back?
