    Need to have a live data scan done on it..If it is running rich will mess the cat up...will not be a 02 it is doing its job.
    Clean the maf sensor..do you run a oiled type filter? Will contaminate the maf sensor.Make sure all is tight in air filter system.
    Check for vacuum leaks.. at throttle body ..vacuum lines ..pcv....check fuel pressure.
