In the 3.1L engine, does the catalytic convertor have an o2 sensor bung in it, or is it before, or after?
Anyone know on here?

We talkin the 3.1 MPFI or 3.1/3100 SFI?
I am quite sure the 3.1 MPFI out of a Cutlass Supreme

If its like my beretta was with the 2.8, basically the same engine different displacement, it had one 02 sensor in the manifold near the collector. Nothing from the downpipe back.
