My. civic 2000 ex have lite on code 420 what do i need to fix problem
From the hondacivicforum.org - "This code generally means that the catalytic converter is toast. Any other CEL codes? Is the engine misfiring?" Buy the cat wholesale online and not at the dealer (Savings $500) and then take the part to a non dealer Honda shop - 90 per hour versus 120 per hour. If you have rust under the car get the heat shields and bolts as well.
