Just had the catalytic converter replaced yesterday, and after 30 or so miles the check engine light came back on, my obd reader gave me the code of p0420, NOW what do I need to get fixed/replaced?

Take it back to where it was fixed as that is a converter code so ther eis probably an air leak prior to converter. Or an electrical issue to O2 sensor

Thanks! I took it back and was told it was "most likely" my O2 sensors. Don't you love how car repair is such an exact science with these guys? Appreciate the feedback, thanks again.
