LS1Z28_98

OK, I tried searching for this to no avail. Seems like everybody had good luck. I put new headers on some time ago. I used the Bosch downstream O2's for a Corvette as my upstream ones. Well, I'm going on my 3rd set in a year. They are not failing in years or months, but in WEEKS. Is there another good O2 out there to use or am I doing somethng wrong or what. I can watch my fuel gauge go down when the O2's fail. Not to mention whats happening to the internals from such a rich mixture. Is this something anybody can suggest?

When they go do they throw the usual o2 sensor codes?


Or is it like a "silent" fail where you just know they're malfunctioning but there's no SES?

That's strange!

I don't think anything's going to work better than the 13111's, you may have problems elsewhere. Can you get us the exact codes it was throwing?

I had the same problem. Are you using extensions? Is it throwing up insufficient switches? Let me know? My problem was the extensions were bad.

I'm not using any extensions, and it is throwing codes. Its 2 codes per sensor, 4 in all. I believe one was that it was switching too slowly. Lemme hook up the little do-hick-ie and I'll get exact codes.
