Hey everyone..so my check engine light came on and I had it checked and it was one of my o2 sensors. The questions I have are 1. I forgot whick sensor was bad do I need to get it checked again or are the two sensors the same? 2. I am doing it myself ( I am not a mechanic but I have common sense and enjoy working on my own sh*t and learning things on my own), will it be much trouble to remove?. 3. Once it's changed will the light go off or do I have to disconnect the battery and to reset it?
