I have a sputterig in the engine, it showed a 420 code and indicated the cat, I have replaced them and all O2 sensors. I am still having issues. I have also replaced the mass air. I am at a loss on what to do, I have reset the computer as well. Could it be that I need to have the computer re flashed or replaced?
