The check engine light just came on my wife's 95 Maxima SE and she took it to the dealer today and they said it was the rear oxygen sensor and would cost upwards of $220 if the dealership replaced it. I need to know where I can buy this part as cheaply as possible and if there are any tips I would need about installing it myself. I am mechanically inclined so hopefully this wouldn't be much of a problem to fix myself. Any info would be greatly appreciated.
