Help! I got P0420
I got engine light and the code is P0420 (Catalyst system efficiency below threshold (Bank 1)). I dont know what that mean. My car have about 58,000 miles. What part do I need to buy to get it fix?
Someone told me that I should buy y-pipe and that will solve the problem, is that true?
Thanks,
