My Corolla had the P0420 code. The fuel line was recently serviced, and then this code came up within days afterwards. This car has been burning oil for years. I have to pour about 10 quarts a year into the car. I went ahead and got the catalytic converter replaced, though I am not sure if this was necessary. The car has 170,000 miles so I assumed that the part probably was worn out.

Cannister for EVAP system intermittently did not work so there would be a heavy smell of gasoline from time to time, and the "service engine" light would go onl. Then when the EVAP system would work, the light would go off on its own and the smell would diminish or go away altogether. I had the cannister replaced today ($650) and will wait to see if this fixed it.
