OBDII code help
Engine light...big suprise, code I get is a P0420, Catalyst Efficiency Below Threshold (Bank 1). Is the companies definition. So what is it exactly, and how do I fix it. If I clear the code, it will stay off for a short time, sometimes longer than other, but it seems to always come back on, and always gives the same code. Thanks a lot to anyone that can help.
