I have check engine lights for just these 2 codes and both say downstream left and downstream right. These would be the ones located behind the catalytic converters correct?
Also are the Walker Products 250-24498 still the go-to replacements? Thanks.

 

Well it’s definitely the downstream. This is probably what blew the F2 fuse that gave me all the troubles earlier. It was rubbing on the front driveshaft.
