2012 Honda Accord P0420 -off and on

Topic starter

Hello, 2012 Honda Accord 150K. The light has been on and off for about 6 months but every time I fill up my tank with gas it will go off for about a day. I am also experiencing a rough idle. I went to the Honda dealership all they suggested was a new car for 1800 dollars. I’m wondering if it could be something small other than the Catalytic converter. Thank you in advance.
