Two questions...

1. Are Bosch O2 sensors REALLY that bad? I can get new ones for about $50 each.

2. How can you test a used O2 sensor to judge if it is worth re-using?


I have 4 used OEM ones...I know 2 have been replaced a few years ago (have paperwork) but all look just as old and dirty. I assume I can clean the tips?

You don't need new ones in the rear. Just ones that function. New (or newest) go in front, old behind the cats.

I have never personally used Bosch O2s, but I have read enough bad reports in ten years to know that I never will.

I have a VW as a DD and a lot of crap under that car is Bosch. Including the O2 sensors I replaced this spring. I've never had a problem. I also put in Bosch O2's into my ex's Plymouth a few years ago.

I've been running Bosch for years on TBI/TPI cars with ZERO problems. They are in my wagon as well, but when I checked the plugs while doing my headers it is running rich and my MPG sucks.

However, the stumble that my wagon had is gone now that the EGR crap has been pulled so there was a problem somewhere in that system. That may have caused the rich condition I suppose.
