do you have your airpump and your acv still in place

simple answer is:

no



unless you have an exhaust gas anaylyzer, a method of tuning your AFR to clean up emissions and plenty of mechanical knowledge to be sure all of the emissions equipment is working properly.

do they have visual inspections in St Louis? that may make your life easier if there is no visual but you will still need to be sure the cat is doing it's job and the fuel system is working properly.

if they do have visual inspections your cheapest and best bet is to just put everything back completely to stock and bite the bullet and hope it passes.

yes they have the drive by things set up, i just neeed it to pass emissions so i can get to school and tech school.

oblio

the way i passed emissions was by connecting the airpump directly to the bung in my single, aftermarket cat. no emissions equip. installed, just blowin air into the cat...

I'm going through the same thing as you except I'm in Canada and I'm not sure how the laws differ between countries.

I have heard a few things about this product called 'Guaranteed To Pass' which is a fuel additive. Not sure if its available in stores in the states or not.

Some friends of mine have told me that they failed their first e-test and tried using this and passed the second e-test. The company offers a guarantee that if the vehicle doesn't pass the test you get double your money back. However this gaurantee doesn't apply if the catalytic converter is malfunctioning/not working or non-existant.

Anybody else heard of this product? Not sure if I wana try it or not haha since I haven't heard a whole lot about it and what it could do to your engine.

here's a link to the product. http://www.crc-canada.ca/Default.aspx?tabid=143

Hope-in-a-bottle. Snake-oil.

The best hope is to fix your car. It costs nothing, NOTHING to go through the FSM and do all the tests to verify that each part of the emissions is working. Haynes Manual has some proceedures that are maybe a little easier to understand.

Fix your car, make it run right and you will have better economy and pass emissions.

If you have a heavily modded car and must pass visual inspection, you can't.

If you do not have to pass visual, you need minimum a known good converter (ie NEW, ask how I know) and good airpump hooked directly to the airtube on the converter and a fuel system in good repair. Half a gallon of denatured alcahol to about 2 gallons of gas in the tank This will reduce the HC results by about 30%. If you cannot pass at this point, you are in trouble.

Good luck

I can tell you something that helps GREATLY. Denatured alcohol. Not rubbing alcohol, but the stuff you get in the paint section of the hardware store. I run about a 1/2 gallon to 2-3 gallons of premium (barely showing on your gas gage). My yearly ritual is fresh oil, new plugs, replace the test pipe with a cat, put on the air pump drive it with the alcohol for about 10 minutes at highway speed to get the system warm, then drive in to get the car tested. As soon as I'm done I fill the tank up the rest of the way with gas to cut down the % alcohol since high concentrations can cause rubber seal damage. Once a year is worth it for me to keep my car. The previous owner removed a lot of emissions related items and this is the only thing that works....
Actual numbers without alcohol HC=3101 PPM, CO=5.5... with .5gal alchohol HC=104 PPM CO=.71%. I have used more and was even lower, but it wasn't believeable results, so I cut back.
AFTER WRITING THIS I JUST REALIZED the previous guy said basically the same thing... I guess I'm seconding what he said!

We have it in America and it helped my gf's pos Saturn pass smog after not passing the first time. Although, I think a similiar sized bottle of fuel injector/carb cleaner would do just as well and is a few bucks cheaper. Besides, I think that stuff is just rebranded fuel injector cleaner anyways.....

Just thought I'd ask because the magnaflow catalytic converter I bought from e-bay doesn't have an airtube provision. Is there any chance of being able to pass emissions on an NA with the EGR and solenoids removed with a brand new cat, without the air tube, using a safc II to lean out the car?

You got the wrong part number; you need a three-way air-injected cat.

Maybe your vendor will let you return, or maybe you could just buy the right one, then resell your wrong part on ebay?

Unfortunately, that's another $100 or so I don't have right now. The administrator of the exhaust forum says that while you can't add an airtube to the cat, you can weld it in to the exhaust pipe in front of the cat and it will serve the same purpose. Any thoughts on this?

Reading Icemark's description of how a cat does what it does and the purpose of injecting air into it, I can't see a problem with it. Even if it shortens the life of the cat, that's acceptable to me. It can't be any shorter than the last one. :P Under 3,000 miles and just over a year.
