Hey Guys,
My short-term insurance was about to expire and it still wasn't passing what we call "AirCare" here in greater Vancouver (BC Canada) so I did a search on this site for some ideas as to how to beat the emissions tests.
Well, I was on the right track and your posts helped confirm what I already thought.
Yesterday I:
- checked and retarded the timing to 6 degrees
- installed new spark plugs
- installed a new rotor
- cleaned up the cap and scraped the posts (parts store didn't have one in stock)
- installed a new cheap air filter cuz my K&N was gross and not coming clean (little owner neglect there)
- removed, cleaned, re-installed the air induction system up to the intake
- ran it on the highway back and forth and held it a 2500 rpms in the line-up to get the (borrowed) cats HOT enough to test (we had lots of snow here the other day, which is rare for Vancouver - yes eventhough we live in Canada! hahaha and I think that factored into the NOx failure the day before)
RESULTS:
MAXIMUMS to Pass g/km = HC = 0.5000 CO = 9.3200 NOx = 1.2400
4. November 30th: PASS! Yay me!
HC = 0.4797 CO = 2.0160 NOx = 1.0965
Did the above "stuff" to the car on my own, outside in the freezing cold!
3. November 29th: FAIL! So close but NOx went way up this time ????
HC = 0.5339 CO = 1.5130 NOx = 2.9976
Figured the cats weren't hot enough and the timing might be out from the shop that looked at it back in June.
Got an oil change couple weeks later cuz it was sitting all summer.
2. August 26th: FAIL! Even with a cheater method ???
HC = 2.5511 CO = 6.7190 NOx = 1.1864
Car sat for 2 months while I was in europe. I ran a tank of better gas and added a bottle of methylhydrate when it was at 1/8th of a tank (recomended by a shop) and drove it (like I stole it) for 45 minutes to another centre. The guy testing the car couldn't keep it on the dyno (launched it off
) and even stalled it
I told then that I wasn't happy with the test results but didn't have time to argue. 
1. June 14th: FAIL! Dammit - seems close
HC = 0.6663 CM = 3.3992 NOx = 1.1316
A shop swapped my H-Pipe for stock exhaust and took it through aircare.
SO! - I am proud to say that I was able to "beat" the aircare system and qualified my pony for a 2 year pass.
I can now put the exhaust back on and re-set the timing to something more favourable for performance.
Now if only the 2 feet of snow we were blanketed with in the past week would go away!
I haven't been on this site much lately but it is Greeeaaaat!
