I threw a code last night on the freeway, looks like it's code 67. The hondata code chart does not list this one, anyone have any ideas what this code means?

 

I get the same code every 300 miles. This only happened to me after i installed my h/e/c. I don't know whats wrong either but the way i get rid of it is by resetting the ecu. Yes i'm a cheap bastard til i can afford an obd 1 ecu. If you check out http://www.c-speedracing.com they have more cods if you ever need help in the future.

#67: Catalyst system Efficiency Below Threshold malfunctioning or defective catalyst system

 

I am trying to put 2 and 2 together. My buddy who is a mechanic said that all the extra air and fuel from my high compression and spec bs make my exhaust gases so hot that it may have burned my cat out. I was also thinking an exhaust leak may cause the ecu to think the cat is not functioning properly. Oh well gotta save up for an obd1 ecu now.

 

Burn your cat up?? I didn't know that was possible...kinda OT but what kinda setup do you have and how much power are you putting out? I want some spec B's but i don't think my motor is ready for it.
