@dustinrulo1988 the P0420 code actually has numerous causes of which all of them could be the cause of your symptoms:
Fuel injectors may be faulty
-
Fuel injector leaks
-
Spark plugs may be faulty
-
Improper ignition timing
-
Powertrain Control Module (PCM)
-
Three way catalyst converter Bank 1
-
Intake air leaks
So, I'd start with the easy one, which would be your plugs and checking for air intake leaks. Most common issue is a failing catalytic converter. Also, you do want to check your O2 sensors and see if they need to be replaced.
