Today my check engine light came on and I went down to the local autozone and found out that it was my front two O2 sensors. Has anyone elso had theirs go out on them?

 

Unless you use leaded gas or a lot of racing fuel (fuel additives) I doubt yours are bad. I would try disconnecting the battery and going from there. I am not saying they are not bad but.......Always start with the cheapest fix first right??
