how many miles and what year is your car. My cats had to be changed last year and I have an 01 with 42K, apparently emissions is warantied for 8 or 9 years and good to 100K along with the PCM. Just a thought, that can be considered emissions to a certain extent. Maybe your cats are bad like mine were it threw P430

Tune out the rears...make sure the fronts are good.
How important are they? Try driving with a bad one...haha.
First H/C swap I did, I had a bad front O2 after the install...car barely ran worth a crap. Bucked, jumped, surged...could hardly get it to run at all...
