I was just curious which front O2 sensors I needed to purchase with the above combination of parts. I thought I read somewhere (can't find the thread now) that there were two different O2 sensors that fit the same plug but one will work, the other will not. I would like the ability to run in closed loop, but wondered which part number to get. Thanks guys.

I have been ok with swapping or using the Rear F-Body O2 in the front.. as the wire are longer.. No problem so far.. as far as I know.. the only different is the length of the wire to the pigtail. (but I could be wrong).

All of the Fbody cars used the same oxygen sensor from 1998-2002.

But are these compatible with a 2001 Tahoe ecu? I just remember reading somewhere about a grounding issue and 2 different o2 sensors or something. Sorry I can not be more specific. I just remember one was effectively grounded by the case the other required an external ground wire but both would plug into the same pigtail.

doesn't matter, if the harness config is for an F-body and the PCM is set up for F-body then use the F-body O2 sensors

Cool, thanks. Hey you ever make it up to the year one show with that Chevelle?
