Mechanics drivin me away - ::Van-Mell-Midis::

If you've come to this site you most likely already know that you have a P0420 code. To start, we strongly recommend you seek the services of a professional mechanic/technician if you have any doubts as to whether you can perform the repair! Also, be sure to follow proper diagnostic procedures to determine whether a part has failed. If you simply change parts hoping it will solve the problem, you're really just guessing and wasting money. This site is here for information purposes only and is meant to help you learn more about the dtc and decide if you can tackle the repair yourself. It is not intended as car repair advice.
