To be sure, call the Bureau of Automotive Repair (BAR) at (800) 952-5210. I have never heard of this requirement, but it does make sense if the state suspects that there are still back-alley smog shops in operation.

First I've heard of that. I had a C4 fail, so I went home, threw seafoam in, took it back and it passed. Never heard anything about it again.

I haven't looked into the code in a while, but a quick search popped up this from the CA "Health and Safety Code" ....

44032. No person shall perform, for compensation, tests or repairs
of emission control devices or systems of motor vehicles required by
this chapter unless the person performing the test or repair is a
qualified smog check technician and
the test or repair is performed
at a licensed smog check station
. Qualified technicians shall
perform tests of emission control devices and systems in accordance
with Section 44012.
You can search the CA codes yourself at ....

http://www.leginfo.ca.gov/calaw.html

Are you performing the "repairs" yourself ??? Not allowed under the law unless you're a qualified smog technician and you are working at a licensed smog check station.

The state has these requirements so that you "supposedly" can't fool the system with some kind of "temporary" fix ..... the state wants the car fixed permanently to not pollute.

You need to be REALLY careful .... two failures of a smog test is getting you into territory where you are looking at fines and other problems. You have to have a seriously modified C5 to fail the CA smog test ..... to do it twice (the state ain't entirely stupid) means you have a car that YOU have modified and made illegal.

You need to pull the mods and get the car legal .... a third failure is not what you want.

Good luck.

What were your #s for the sniffer test? A big cam is about the only thing that should make you fail unless you really do have some missing or faulty emissions equipment.

No person shall perform, for compensation,
I think the intent of the law was to "protect" people from crooked (or clueless) shops changing out perfectly fine smog equipment. Notice the "for compensation" bit. You don't work on your car "for compensation."

If you failed the sniffer, you can add a 15-20% mix of xylene to your gas. It will clean it right up. After the test, put some good gas in there.
My 944 failed miserably. When I ran the xylene, it was a "raised eyebrow" because it was so clean. (technically, it went from 1200 ppm, to 80 ppm... passing was 750 ish)
PM me if you want the charts and details.

Does xylene have any harmful effects on your fuel system/cylinders/cats/O2 sensors?

Just so you know and I passed smog TODAY and have the results in front of me, the requirements in CA now are 100 PPM at 2500 RPM and 130 I'm pretty sure at idle!
I don't know if the standard has gone up but I'm sure that's what it is as of today.
Your car should pass man, just either get a really good tune REAL quick or put the exhaust manifolds/cats back on the car and just keep it legal. BlackZ06 is dead on right!

Unfortunately for the OP he's in an "enhanced program" area because ....

44003. (a) (1) An enhanced motor vehicle inspection and maintenance
program is established in each urbanized area of the state, any part
of which is classified by the Environmental Protection Agency as a
serious, severe, or extreme nonattainment area for ozone or a
moderate or serious nonattainment area for carbon monoxide with a
design value greater than 12.7 ppm, and in other areas of the state
as provided in this chapter.
The requirements in Oakland are probably lower (tougher) than in the Redding area.

A stock C5 is VERY clean ... it is well within the limits (like 10 percent of the limits) for NOx, HCs and CO ..... so you have to REALLY screw the car up to get it to fail.

Precisely! The strong arm of CARB and BAR have not gotten to the point where the owner of a vehicle can't repair/replace parts on their own...at least not yet.

On topic, the OP may consider contacting the Bay Area Air Quality Management District (BAAQMD) at (415) 771-6000. They are the local agency that adopted and require this tailpipe emissions test. Their office should have a staff person that can accurately answer your original question regarding any requirement to specify what was done to pass the test after two failures. Out of curiosity, what part(s) of the two tests conducted have you failed?

FYI, you can pay for and have a "pre-test" performed at a smog test station. This may prove useful in determining if whatever improvements you make have been successful. The price is less than a full test AND most importantly, the results are not electronically transmitted to the authorities. Trust this is helpful...

Here's the strange part:

The state has been LOWERING the max HC emissions over the years!
How can they do this?

Not in a small amount like that, and you're only running it for a very limited time. It is also used as an octane booster. There are 'home grown' octane booster recipes all over ls1t.

Here. I dug up my old post about this. This chart was on my 944 which failed miserably. As you can see, the "after" was much cleaner. The two other things that were done at the time (although I doubt it needed to be done) was 1) I changed the oil. and 2) I got the engine good and hot by unplugging one of the two fans.
