Dammit! My daily beater failed emmisions badly. Here are the results.
ASM2525 test Curb Idle
HC PPM limit 75 reading 232 limit 200 reading 267
CO% limit .42 reading 066 limit 1.00 reading .25
NO ppm limit 576 reading 1368

I HAD a code 67 (cat converter code) which went away after I installed a different 02 sensor after the cat. I think it's time for a new catalytic. Anyone care to shed some light on my readings?

Thanks allot for you time.

thats not so baddddd!!! lol i failed by over 4x the limit on everything hehe well maybe it was 3x lol change your oil plugs, run some higher octane gas(for atleast a full tank) they will lower your emissions slightly and it seems likme you need a new catalytic! good luck

Mr.death

The engine is a d16y7 which has the cat built into the exhaust manifold. I guess I need to purchase the combo togeather or no? Grrrr.

Well high CO is most likely a fuel delievery problem. Sure none of your injectors are leaking?

And did you data-logg your o2's? Have you also tested the function of the catalyic convertor..

Mr.death

Fuel delivery huh? I posted this earlier on another thread(maybe related), when I checked my plugs prior to my e test plug 4 had lots of carbon build up while 1-3 look o.k. When I took out injector 4 last week it looked dirty as hell near the plastic tip. I soaked injector #4 in an ultra sonic bath of injector cleaner hoping it would cure my carbon build up prob as I figured injector 4 was not spraying properly causing unburnt fuel to soil cylinder#4 and foul the plug. As for 02 data logging I did nothing of the sort. I had an extra 02 laying around so I threw it in after the cat hoping it would get rid of my cel (code 67 catalytic) and it did. I did not test the function of the cat. How wold one go about that?

chris_v2

fuel delievery=Fuel inj. system, so sensors, injectors, pump, etc.

To check a cat yuo need speciality tools unforunately. Weither it be a data logger, lab scope or a thermo-gun.

Honestly, I would bet that you have a bad injector, weither it be leaking or staying open a bit longer. But once again, you need speciality tools to test (an FPR). Prime the key, FP should rise to 38psi (apprx.) and it should stay steady. If it starts to slowly drop down you got a leak.

if you fail everything you cat is usually to blame, cause the odds of you passing with no cat are VERY slim!
swap it out run it for a day (daily driving) then take it in for a test again. should pass flying colors. also best thing to always do before e-tests are oil change and plugs.

just my 2 cents being a certified emissions tard.

Mr.death

I did the oil change and plugs. I think the cat in done for. It's a d16y7 so the cat is part of the exhaust mani which means I need a whole new exhaust mani/cat combo which will cost allot I imagine. Ughh. Hatin life right now.....

sol_searchin

you can unbolt the catalytic from the manifold and replace the cat or go aftermarket

Nicotine

for what the combo would cost you, you could get a decent after market header then do aftermarket cat, and it would cost you less.... or you could even do a cat mid way in your current exhaust, and leave the cat you have in place - but do the new cat on flanges, so you can swap it in and out (replace the cat with a pipe after etest)

Mr.death

You cannot unbolt the cat from the exhaust mani on a y7 as they are one piece units.

chris_v2

If you have a emission cert. you would also know cat's don't just fail. something caused it to fail. Hopefully when Rick changed the plugs, oil change and cleaned his inj. fixed his problem.

chris_v2

Rick... go to an exhaust shop that does cats. They will cut the old cat off and mig on a new one.

Last time I did one on a y7 at work it cost my shop $160.

if your cat is FUCT! your car will fail, you can swap a new motor and it will still fail. if the cat is shiet you will not pass unless you change it. and it will fail everything on the ASM.

if you knew what you were talking about you wouldn't jump to conclusions. are you a certified inspector? cause i know alot of them wont say shiet about it cause they want you to spend more and also steer you in the wrong direction cause there not allowed to tell you what the problem is or give hints, just hand you a brochure and say have a nice day!

been a member here for a good almost 2 years and know next to everyone, and dont give a shiet about my job, so what ever i can help anyone out with related to it i will do so. except yourself

Mr.Death post a wtb ad, or find someone from here with a spare one, swap it in test it ( providing its good ) and then swap you old one back and your good for another year. just my 2 cents.

chris_v2

why are you quoting me?

"been a member here for a good almost 2 years and know next to everyone, and dont give a shiet about my job"

youve been a member on tcc for 2 years, you know everyone and dont give a shiet about your job? wtf... lay off the smack

Mr.death

Well, I went to Zorro muffler today and the guy quoted me 500 to have the cat/mani replaced...I choked out loud in front of the guy. Thanks but no thanks. Anyway I put up a WTB thread for a y8 exhaust mani so hopefully someone will reply then I will have a new cat installed on that and have my injectors professionally cleaned and tested. I found a place which cleans injectors for 25 a shot. Not bad IMO. I should be good after that. I hope.....

chris_v2

Rick.. where you live? I can have a quick look for you and give you a better indication as to whats going on.

cleaning injectors at this point is a waste of money imo, since the only way it would be related is if they're so badly fouled that the fuel atomization is really bad and thus the air fuel mixture doesn't mix very well and you dont' get complete combustion, but if that was the case you'd have spots in the combustion chamber that are really hot (since they have a lean mixture) which should also cause your NOx emissions to be high.

I would check your ignition timing with a light, check for a nice hot (blue) spark on each spark plug, and verify your fuel pressure. is the car modified at all? is it running Y8 injectors by any chance? (Y7 injectors are smaller than Y8 ones) how much history do you have with this car...

it could be the cat, but for me, it's usually the last thing I'll replace. I do a lot of diagnostics before I go out and blow $500. BTW, you can get a replacement Y7 cat from like NAPA or some other parts store ... and swap it yourself. Even better, go to Auto Zone in the states and get one, with the exchange you'll prolly save some really good coin cuz replacement parts from Pep boys, AZ, and places like that are really cheap!!

Mr.death

Awesome. I live in Etobicoke but I'll meet up with you wherever whenever if your out of the area.

Rick, its good to tune up the car anyways, since its old, you'll have it running awesome,as well as save on fuel.
give it new:

- fuel filter (cheap)
- spark plugs/wires (cheap)
- Distributor cap ( very cheap)
- PCV Valve (very cheap)
- catalytic converter (only expensive thing get one at partsource $189)
- 02 Sensor (very cheap)
- new air filter (very cheap)

Also, check your timing to make sure its not running rich etc.
btw, if the car aint passing, it could be burning oil .. which screws up everything.
