How urgent is p0420?

lundi 7 avril 2014

P0420 code is being thrown. Will continuing to drive on it mess things up significantly. Going to be changing out the plugs and ignition coils as soon as I get them from mazmart. I know that won't fix the issue but will maybe help avoid it in future after fixed.



If it's clogged cat which I'll check when do ignition change, can I just gut it til I buy a new one. At least won't have a bad cat to help mess stuff up. Don't have emissions for a year and have always wanted to check out the gutted cat.
