Emissions Test (nf)

[xrap]

Our Honda civics jsut went for a emission test and it had one thing failed. It says no ppm and I went to the driveclean.com website and searched ppm but I don't really understand what it means. Can anyone explain it to me a little better?

I thought ppm stood for "parts per million". Each emission (eg Hydrocarbon, Nitric Oxide), has a threshold of how many ppm is acceptable. If it's over that amount, that part of the test fails.

Remember, its important to drive your car for a good 20 minutes, preferably some type of hiway driving, before taking it to get tested. Better chance of it passing then.

Yep, your right hooked. I told my brother in law to do that but he didn't and jsut yesterday he poured a bottle of engine injector to clean it out a bit and the smoke from the exhaust was coming out white. Bad idea, and now he''ll be paying for it again.
