Yes I reccomend that they be replaced... But again, and I have said this many times in the past.... If your milage has not changed at all, or gotten any worse than its well enough left alone...

I have had 2 very bad O2'*, one on the 91 and the other on the 95.... Neither ever set a code... Worst milage I got was 13mpg... Normally 18-20...

To each his or her own, if you want to replace the sensor thats fine...If you don't thats fine too...

And do you mean OBD or OBDII ?

Over the weekend I took a little trip (110 miles) all highway, and got 27mpg.

27 Mpg falls into the normal area... Replacement of the sensor may help you a bit...

Yor car was rated 18 city and 28 Hwy... It can vary with driving speed, conditions and the like... But generally these cars tend to do better than the rating on the open road... 27 is not bad...
