    So a while back my catalytic converter went out on me, it was completely done. The shop where I have all the big repairs done told me to bring it in and they would straight pipe it as that would be cheaper than putting a new converter on. So I did and as expected I am popping up a few check engine lights. One being PO420 and the other being PO133 which both have to do with my catalytic/o2 system. CEL lights usually don't bother me but these have been on a while and I'm thinking they are making my gas mileage go down. I've heard of dummy o2 sensors and was thinking that might fix the problem. I was wondering if anyone could give me a suggestion of what to do.
