Unhappy FAILED inspection

Got my car inspected today and failed emissions.

Here are the aftermarket goodies:
UD pulleys
K&N Filter, custom Intake
Borla Headersand exhaust

I still have the stock cat on the car, and all the stock exhaust pieces in boxes in the garage. If I put my old muffler and midpipe back on, maybe reset the ECU, would I hopefully pass?

somethings not right here, why did you fail?? they had to have given you a reason.

seeing as how no state except cali uses CARB approval for modification.

It might be your cat.

I failed emissions twice here, and everything is "normal", and my mechanic deemed it to be the cat. Anyway, he leaned out my fuel computer like crazy and the car passed after that.

what are the readings on the card they gave you? what did you fail co, hc, nox?

I passed NJ inspection with a jcsports intake, and stromung cat back with flying colors, close to zero emmisions, I think HC was around 6.

HC reading was 589, standard is 100
CO% was 5.01, standard is 0.50

They had the car in neutral and held the engine at 2500 rpm because the facility lacks an AWD dynometer.

I have been filling my car with 89 octane instead of 87, could this even be affecting it? Or should I reset my ecu again? I definitley think that the car runs very rich at low rpms, exhaust pops quite frequently and the inside of the pipe gets very black after a few drives.

!, my CO was 0 and HC was 6.

was the car fully warmed up?

I know how they do the test, the dumbasses started to dyno my car untill I started screaming at them, then they tried to tell me to calm down...idiots

If your car was fully warmed up, where you waiting in line for a long time?, your mods should have no effect on emmisions, take it back, if it fails again, take it to your dealer.

McDade and JadeMonkey are totally correct, esp. on the warmed up part...
...always have your car warmed up before getting the emmissions checked, friggin keep the engine on and leave it running....the cats use the heat to burn all that leftover stuff up...
thats why wrx has 3. To pass the import emissions test (@2 minutes from cold) and get a LEV rating too.

FWIW warmed or not a car with a properly working cat should not have 600 HC @ the tailpipe when cold, 200 would be the max i'd want to see, i know these cars run stupid rich but unless the car was started from 100% cold it should not have that kinda HC @ the tailpipe.

Hell yeah my car was warmed up, I was sitting in line for 2 hours! I got the car used with 3380 miles. Right now it has 13700 and I changed the oil 700 miles ago. Haven't changed plugs yet, thought you do that every 15k miles.

pillaka you had better have your car re-tested, something tells me they REALLY screwed it up. If you have no MIL's(check engine lights) and your car has that few miles then it had to be their mistake, i've had the illion air team test my truck as an 86 toyota corolla and it failed miserably, the people working at those places aren't the smartest.

Are the emissions components still under warranty? But yeah, somethings really screwed up somewhere.

I can attest to that. They tried to dyno my MR2 using the front wheels (Morons, its a RWD car) Not only that but when I asked how they test AWD cars, the guy told me "Oh a 4WD-er. That's easy. Just push the button, to put it in 2WD, and run it like a normal car."

After I told him he was a moron, I asked someone else.

check to make sure you have a good vacuum line on your FPR. If it's leaking or plugged, you'll be running super rich.

Just a thought.

VERY good point, those readings had to be because of 1 of 2 things, 1 you were still in open loop mode and car was cold or 2 the vacuum line thing...

(my 82 jeep with a 360cid engine had a edelbrock performer intake, edelbrock cam,(disconnected EGR, and AIR pump) and a holley fuel injection kit. first inspection failed by .01 on CO, all i did was tweak the fuel trim and i was done.)

Every inspection place knows not to put a late model Subaru on the dyno, they have a list of cars in there office that their not suppost put on the dyno. I would have kept my mouth shut and let them trash my car, Would have loved to see the rear tires light up and blow up my drivetrain! Free new parts & a lawsuit

and in the mean time you have to foot the bill for over $6k worth of repairs until you beat them in court

sorry i watched a car hop off the rollers at speed, that's very interesting. And those people make $7.50 an hour, as far as i am concerned, you get what you pay for.

Could you possibly get those high of reading if your O2 sensor was starting to go?

After working with the State of Florida's now abondoned emission testing program for 5 years...check this:

Quote:
K&N Filter, custom Intake
If the ECU "reads" a whole lot of extra air it will dump more fuel to reach the preset ratio it is trying to maitain. You may have a leak in your intake configuration that is allowing more air in than the ECU is expecting. Or your O2 sensor may be malfunctioning and telling the ECU it is reading more air than really is there.

Well, driving to work this morning my check engine light came on.
Here's what I've read here and thought up:

The 02 sensor could be bad.

The car could have been running like this for a while and the rich fuel destroyed the cat.

Custom intake and aftermarket exhaust could be messing up the ECU. (I did reset it twice though when performing these mods)

Sometimes when I start the car up, and drive around before the engine is 1/2 warmed up the idle stays around 2k rpm.

Think I found the FPR but not really sure, hose connections look good but didn't inspect the rest of the lines.

I also pulled out my plugs to inspect. From the pics I gathered from various websites, by the coloration of the plugs the engine seems to be running "normal". But there was some black soot around the threads and electrodes. So maybe the engine is running rich.

As soon as it stops snowing and my driveway is dry I'll reinstall the stock parts, reset the ecu, inspect all the vacuum lines, and see if that fixes the problem. If not I'll go to the dealer since my car is under warrenty and let them try to fix it.

Do you have a rough idle?

When my 1991 SE-R had high HC (228 and max allowed 200) we went looking for a MISFIRE as the cause of the rough idle & emissions. It took injector cleaner (had lean plugs) replacing my plugs, then wires, then distributor, then rotor to pass. Of course we have distributorless ignition on the Subaru.

High CO2 can be a vacuum leak into the intake.

Cats/O2 sensor are the least likely to go, but you should check that CEL code for more clues.

You said you have a CUSTOM intake, does this custom intake use a Mass Air Flow sensor? A little obvious but just trying to help.
