o2 sensor

has any one here had to put in a new o2 sensor like every couple of months

you shouldn’t need to replace the 02 so often. I just replaced my first @ 215K miles and it still looked good.

What makes you think you should replace? What kind of signs are you gettting?

im starting to get a little bit of the hestiation that i had before i replaced it in the winter
and i was getting this poping sound that stoped when i put a new one in
