My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
With the 420 code that set this may be a restricted catalytic converter needing replaced.If you have not had an exhaust back pressure test done I would have this done to see if the catalytic converter needs replaced.Normally you want to see no more then 1.5 psi of back pressure at all engine rpm's.Anything more then this indicates it is plugged needing replaced.
Thanks Pete
