Question

Got a 1998 Honda CR-V 2.0L. I retrieved a p0420 and check engine light is on. What should I do?

Answer 1

p0420 is usually for a bad catalytic converter

are you using 91 octane fuel? if not I suggest you switch to the higher octane fuel

Fill up from Shell and use a good fuel system cleaner, you might get lucky and not have to replace the catalytic converter
