basically i was just cruising like 40 mph and all of a sudden it goes off.
its never gone off before, and i have about 40K miles on it. it idles fine, and everything seems fine..but i cant seem to find out what caused it. does anybody have a clue what it is, or what it could possibly be? any info appreciated. thanks so much.

Check the code y0.

k so i found out it was code 67..and its "Catalyst system Efficiency Below Threshold malfunctioning or defective catalyst system"

so basically a bad cat...?
do i even need to replace it?

 

get an obd1 ecu, and jumper, there will be an indefinate code of "nonexistant" after that. LOL

thats my way of solving things these days, i swear im fuckign lazy


good luck

 

same here haha

driving the car won't harm anything right? this sucks...first time carsound started rattling..now it makes the check engine light go off...carsound blows

 

f0k MIL's!

i'm driving w/ #67 and #1467 codes

 

carsound cats are good, but since R's run rich, it will definitely go out sooner than expected. if you get her tuned, i'm sure the cat will last lots longer.

do you have a high flow cat? mine threw that code all the time. the reason for the code is that obdII cars measure the differnece in exhaust gases from the first to the second o2 sensor. if the second reads too close to the first one, check engine light. the car will run fine, it is not a limp mode code. i solved my problem by getting a obd1 kenji chipped ecu and jumper harness

 

So wait a minute....j00 are complaining about it going off? If i were you i'd be happy it FINALLY went off

Edit: after re-reading the title...i think you ment "check engine light has come on" , right?????

I was thinking the same thing. I'd love it if my check engine light went off.

 

yea it came on..my fault

and yea its a high flow carsound cat

 

Do you know which model Carsound you have? Is it 2.5"?

 

Take out your bulb.

 

Make one of these:



I believe Black R was making plug in and play versions of these. Don't know if he's doing it any more.

 

Homemade o2 simulator? I don't have the ***** to start cutting wires on my ecu.

dats what I did a long time ago. I'll only reinstall the bulb when VTEC wont engage.. which has been never so far.

that's the wiring after the O2 plug, between the plug and the sensor, not the ecu wiring.

 

yea its 2.5..i guess ill just take the bulb out for now..or just leave it be..who knows

if you take the light bulb out, there may be other codes being thrown later so just check your codes every month or so.

That's the first thing I saw too.. I was gonna reply "Congratulations!!!"

Usually, driving on the CEL isn't bad. Don't push it until you know what it is.

 

make the home made o2 sim or go buy one, that **** is gonna eat up ur gas mileage

POS cats.

 

UPDATE

It will probably come on again.
