    Have read that if you choose to replace the Cat. Conv. with after market, non-toyota parts, there is a very good chance that in 6 mos, the same issue will reappear. (Check Eng Lite code p0420)
    I have already replaced both o2 sensors. I also spoke to a mechanic (certified toyota..) who opened up his own garage after working at a stealership for 10 years. I would rather feed the "little guy", and he too suggested that the same was true. Any experience out there?

    Any issues with performance/gas mileage with a simulator? It replaces the rear o2 sensor?

    It plugs right into the old sensor, i get 16 mpg with my 33's and my driving style so i think thats pretty close to normal.
