    02 sensors??

    about a month ago my ses light came on so i plugged it into my scanner and 2 codes came up for 02 sensors low voltage. I erased the codes and they havent came back since. however the other day the ses light came back on and this time it read that my cat was clogged. I bought a new high flow cat and i was wondering if my 02 sensors should be changed before i install the cat or should i just leave them?

    good idea to change them out, but the aftcat ones. If not, just get the stuff to clean 02 sensors and be done with it
