Do you agree the cat is bad? Or is there more diagnosis I need to do with O2 sensors?
Also, I am confused now because I thought the cat that would need to be replaced is the one that is combined with the manifold. Going to buy them off another member on here today but reading another post was saying the threeway cat is the bigger one further downstream? I thought the cat that is the one closer to the muffler end is unmonitored?
