    Run scan data to determine the operating function of the fuel trim, and correct it.

    A P0420 has nothing to do with fuel trim. The wonderful USA government mandated that the manufactures have to monitor the cat efficiently. I think cardoclll is correct, you don't have the proper cat on.

    Where did you get the catalyst, and was it CARB OBDII approved?
