Having problems with your 2000 Oldsmobile Silhouette ?

I have not been able to find the oxygen sensor that is before the catalytic convertor. Do you know where it is?

Good Evening, I am sorry to hear you cannot find the upstream oxygen sensor. Unfortunately it is a difficult one to get at from up top because the way that the firewall sits over the top. It is on the back exhaust manifold, if you were to able get underneath and could follow your exhaust pipe up to the engine you can see it. I hope this helps, and if you have any more questions let me know.
