Bad 02's?
 

Would bad 02's cause the car to idle strange sometimes? Im assuming yes, as my check engine light came on about 1 week ago. I got the code checked and its the 02 sensor on the side of #2. Anyway, i havent seen any problems since, untill this morning when i turned the car on and it idled at around 400-500rpm then a few seconds later it jumped up to correct itself. Anyway, im pretty sure the (at least one) bad 02's would cause this, I just want to know if there is anything else that could be causing this?

You know... the more i think about it, the more im sure my 02's are messed up. I drove around for 1 1/2 months with my long tubes and no cats running so rich that it stained my tips yellow... Im gonna replace the 02's soon.

I just had the same problem... My car was running really rich for about 2 weeks..

A/F guage stopped working and the car ran like crap.. Bit the bullet and bought new O2's..

Problem solved..

I saw a post the other day about possibly getting rear corvett replacement 02's because the wires are long enough that you dont need to use the extensions any more. I think the problem might even be that the extensions are letting watter in and messing with the input. Has anyone done this? Any problems?
