Just got a CEL on the way home, code 67. the description of the code is Catalyst performing below threshold, i assume this means that i have a bad O2 sensor. any way to tell which one it is?

Any ill effects of letting it run this way? (I.e., will the car dump tons of fuel in and hurt my performance?)

thanks.

 

actually, it either means your cat is bad or you have a high flow cat

 

I have a high flow cat, never had that come up before though. is the CEL hurting the performance at all?

 

what steve said. and no, no effects from it. I've had a code 67 for uhmmm.. well.. a long time now. 1.5 years I think..

 

sweet, thanks for the help guys.

 

John - just reset the ECU. It'll go away and probably won't show up. Sometime humidity and temperature plays a part in cat's poor performance. It has happen to me on two separate occations, but never had the CEL for more than a few hours. It never came back.

 

hehe .... sounds like it's time to get a Hondata or Mugen computer.
A nice solution to a cel problem.

 

judging by your parts pictures, you're loaded, care to sponsor me?

i'll put "ZYGspeed owns me" stickers all over my car.

 

I've been reducing inventory lately.
Reid bought my Mugen ECU already.

I might have a stock radiator to spare shortly.

 

CEL 67 means you sold out a fellow type R member.

 

Don't get rid of it yet.

 

It's always something!
OK, I may have a C&R twin fan set-up for sale!

 

try replaceing your cat. i got the dealership to do it since i still have warrenty and it fixed the problem.

 

he has a high flow cat.. the dealership will laugh at him
