Check engine light front right o2
Just had my dif fixed and on the drive home the check engine light came on. Naturally I called the shop and was told it was a faulty o2 sensor. So instead of having them replace it I order one online to do myself. I order the Bosch upstream recommended part and install without a problem. My buddy who is a mechanic helps and resets the code. After driving for 10 mins the light come back on. We plug it in again and the same code comes up. Also, when we accelerate with the new sensor it does make the number jump on the faulty side. Any recommendations? We are thinking a faulty sensor and gonna try a new one. Anything we misssed or could also try?
