1998 Integra, 4dr auto with B18B1 DOHC engine.
Started getting a"check engine" light a few weeks back, so I pulled the
code.
It flashed a 67, which my Haynes book tells me is Code P0420, with probable
cause "Catalyst system efficiency below threshold".

Is this serious? Expensive?
Anything a DIY mechanic can handle?

TIA for any advice!

your cat converter is bad. I think Honda has an 8year/80000 mile warranty on
cats.
