Angry Failed smog test...

My family's 1996 Honda Civic LX with 153K miles just failed smog for high CO and NO emissions. I just replaced the spark plugs, front O2 sensor(went bad), air filter, and oil change about 1K miles ago. I let the car warm up for about a good 7mins, drove to the bank and which is about a mile away and then to the test place which is about a mile away. I only stopped the engine once for a minute to talk to the guys and then let it idle until the test(5mins max). I know I should have driven the car harder to let the cat get hotter.

CO %
Max Ave. Measured
.57 .02 1.66

NO (PPM)
Max Ave. Measured
487 57 585

HC(PPM)
Max Ave. Measured
66 9 26


What do yo guys suggest?

What's the law on replacing a cat on an OBD2 car?

Are my numbers that high that the problem is the cat?

I laugh, because even my rotary pulled off clean numbers!

MA has the most stringent tests, equal to CA...and oddly enough, my RX-7 had the cleanest numbers I've ever seen.

We won't talk abotu the RX-7 I had in high school. Blew a cool 1600ppm on the HC

As long as it is CARB approved you should have no problems.

I don't think there are any OBD2 CARB approved cats.

Yes, there are. There have to be because according to federal law a cat only has to last 50K miles. They do not last forever, go to a Kragen or something and ask them about your options, there are definitly cats that fit your needs.

Please note that no aftermarket catalytic converters are legal for installation in California on OBD II vehicles (some 1994 & 1995, and all 1996 and later vehicles).

junk yards here aren't even allowed to sell cat converters from wrecked cars.

Drive it around for like a week, doing your everyday thing.

When I had my 240, it sat for 3 days then I drove it hard on the way to get emissions and it failed. I then drove it the next week for all my everyday things and it passed easily.

I was getting a 41 CEL, which was front O2 sensor heater circuit malfunctin. I replaced it and the CEL went away. The car could barely idle with the bad 02 sensor, do you think it damaged the cat?

Should I buy a used cat on the Honda forum?

When I failed for NO emissions on my truck, I just filled it up with Super and retested.

That did raise my HC's and CO levels to almost non-passing, but I slipped by.

You should definitely run longer before the test. That's not nearly enough time to get the engine & emissions components up to full operating temperature.

I dont know what to tell you then, catalytic converters aren't made to last forever and should not be expected to.

Inquire at a muffler shop, or at a dealer. Saying you can't replace a defective part is rediculous, get an OEM cat. They're spendy, be warned...


I love where converterwarehouse says: Catalytic Converters are required, by law, on every motor vehicle operated in the United States after 1975



No they're not. I know for a fact that my 1986 Dodge didn't come with them from the factory and isn't required to have them.

They also aren't required by federal law after 50K miles.

Get one that is CARB approved and you will be fine. I think the random technologies high flow cat has a CARB sticker.

ok if your O2 went bad then it's possible that your cat is messed up.
I know you just changed the oil ~1000 miles ago, but change it again right before going in.

also replace the PCV valve
and spark plug wires if they haven't been changed recently
I've heard that there's some stuff you can dump in the oil to help emissions (temporary fix) as well.

In Washington you pay for every-other emissions test when you fail.. first one, then the second one is free, and so on.

Oh, before doing anything, take the car out and flog the bloody hell out of it, run some injector cleaner and some stuff to remove carbon deposits through it as well.

But if the front o2 was bad for any period of time I'd bet you need to replace the cat.

I think there's a part missing from there. Although it says you can't replace a CAT, but you can replace it ONLY if the cat isn't working anymore. In other words you can't replace the CAT when it's in working order, but you can when it isn't.

Well thats how it is in Cali.

that's how it works in the rest of the world too. er, res of the states. 5 years, 50k miles or later and you can replace it unless it fails before hand.
