i am thinking about getting some new o2 sensor's. i have about 107,000 miles on my car. scans show that my o2's are shot. my question is, can your o2 sensor's be shot but still have decent o2's at wot?

What did the scan display that caused you to draw that conclusion?

at idel the o2's are extremely low. they stay around .010 or so. my car idles real rough and crap but than when i went wot, the o2's were a little ok, i mean, i am still lean, but i am only seeing a couple degrees of knock. i'm just curious.

O2's should be all over the place at idle, check your ltft's at idle, I bet they are maxed out if the O2 is staying low. Stick with an AC Delco sensor, I picked up a new AFS-109 AC Delco sensor for $45 bucks through an e-bay store, local dealer wanted $120.

Just buy the front one, at 102,000 at the very least you should pick up mpg.
