08 subaru catalytic convertor

my 2008 Subaru forester has been throwing catalytic convertor codes for the last week. It doesn't seem to be down on power however the cruise control doesn't work while the code is registering.

P0420 means the exhaust emissions are not being correctly reduced.Most of time the converter is bad even if you have full power.A Subaru vehicle will not allow cruise control to operate with a code stored.Do you have any other codes or problems?Exhaust leak?Rotten egg smell?Last oil change?Dirty air filter?Oil on the mass air flow sensor wire?Usually it's the converter though but they ain't cheap and usually go bad because of something else that may have happened in the past.Could be you have high mileage on it,I don't know.
