I have a 2003 Impala with a 3.4L engine. Recently a code 420 has kicked out. Can anyone relate to me what this code is and what are pssible causes for it? Thanks for the help.

When your car throws a P0420 code it means the catalytic converter is not operating properly. Odds are you will need to replace your catalytic converter. Depending on your mileage it may be a warranty repair under the 8 year/80,000 mile emissions coverage or you can get an aftermarket down pipe.
