Catalyst efficiency below threshold (bank 1)
do i need a new cat?or maybe just an o2 sensor problem?

 

i have the same code popping up and i took it to the deal for diagnostics and they told me someting is dumping too much fuel and is burning my cat up...somehow i dont believe it and everybody else is telling me 02 sensor...so i dont really have much info to give u otherwise i would hook u up...
