my emissions was acting up so i had ran a diagnostic. it said that the downstream o2 sensors was all messed up so i had replaced them. now the check engine light had come back on and i ran another diagnostic and now it gave me a code of P0430. it says that the catalyst system low effiency bank 2 is bad. i dont know what that means or what the means are of fixing something like that.
