Failed Aircare
Can anyone help me out with what i can do to fix the problem?
allowed idle
hydrocarbons 345 2000 FAIL
(PPM) allowed 40km/h
198 108 PASS
Carbon Monoxide allowed idle
(%) 3.91 .12 PASS
allowed 40km/h
1.38 1.42 FAIL
Oxides of nitrogen
(PPM) allowed 40km/h

I was running 87 octane fuel and i added "Guaranteed to Pass".
edit: it won't allow me to place large spaces between numbers

Re: Failed Aircare (battsup)
Hey Sonny,
2,000 parts per million hc's is REALLY high. Your way too fat at idle. Try leaning the carb out, make sure idle isn't too low or too high. Do this before you start goofin' with the timing or anything else. Do you know a local shop that has a 5 gas you could use while making the adjustments? If you just guess it'll be hard to get it in spec.

Re: Failed Aircare (battsup)
Been there, done that!!! I insure mine up in Squamish, so no air-care. What I've done to get other cars through is: lean out the carb, retard timing alot ( it will run terrible, hotter and will be gutless- readjust right after test) and burn the 94 octane from Mohawk.
I've often wondered about getting some racing fuel to bump the octane way up. It should burn hotter,faster & cleaner, but I'm not sure about this, maybe someone else can offer they're $.02 on this. Corvette Specialties in Surrey sells Sunoco race fuel if interested, or maybe theres a closer place in Langley.
Can you at least get the 3 month conditional pass?
:cheers:
Dave
P.S. It's my 100th post!! :party:

Ya i have the 3 month conditional because last time it went through aircare(october 1993) it passed with flying colours. O Dave i checked on doing what you are saying but now icbc insures u upon where your car is parked at night so if it gets stolen at your house then your not covered.

Re: Failed Aircare (battsup)
I have a good anti theft device: locked gate on driveway, 2 german shepherds with appitite for lowlifes, vette parked in locked garage, ignition wiring reworked so it will only start with very well hidden switch in proper position,plus the dogs will have woke me up by now so our would be thief has to deal with me and my weapon of choice.I'm not too worried about the car getting boosted from here,and I have an address in Squamish to keep ICBC happy, they think I am working there for the summer,which I am, buy only a couple of days a month.

Well thats good, I doubt i will meet you at street legal though, another caliper started to leak and i cant remove it because the trailing arm is bent. Im gonna try to take a torch to it and bend it back. $597 for a new one!!! or i wait 3 weeks and spend $389 or sumthin.

Re: Failed Aircare (lyndave75)
I understand what you're saying but be careful on the high octane fuel. If you go too high those hydro carbons will shoot to the moon again. When I run through smog down here, I usually use a mid grade or even regular fuel to get through smog on a high hc car. Also a good and common trick down here is to add a plain bottle of rubbing alcohol to your half tank of fuel before you go through, this can help clean up those hc's.
