I bought my car in DEC. 2001, I took it for itz first inspection yesterday...but it failed the emissions!!! They said the carbon out put was too high...almost double test limits dont remember the exact numbers...

Any ideas???

IIRC, retarding the timing a bit helps with the carbon output.

Hydrocarbons, carbon monoxide or carbon dioxide?

If it's hyrdocarbons, then retarding timing will help a bit, but you probably need a new cat.

i agree with duffy...replace your cat, and if you have a filter...swap your stock one back on....you should pass then...

Aren't you KA-T? I'd say just find a shop with no soul and slip them some money <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='

Bad catalytic, weak ignition, bad O2 sensor.

Yeah datz what i did, i went to a diff. shop and just "bought" and inspection cuz it already expired last week.

I forgot carbon what but on the sheet is was listed as: "CO" i think the test limit was 18.2, but the test results were 30.0. Almost double.

You might want to study some basic chemistry. "CO" is Carbon Monoxide.
