I have a 1991 Civic Wagon RT4WD. When I bought it a few months ago, it failed California emissions. All the emissions were very high. So I changed the spark plugs, air filter, and used CRC Guaranteed to Pass. Then took it back for testing, and it passed with flying colors...all the emissions were very very low, well under the maximum limit.

Re: Passing emissions issues
<p>You get a check engine light so obviously you won't pass. even if you happened to pass the sniffer test, I think they can fail you simply because of the check engine light.</p><p>did you pull the codes to give an idea for the the problem is?</p>

OP, pull your codes and fix them. Also, if your car is a dx or hf, chances are it might not pass with a z6. My std couldn't pass with an a6 mpfi swap, even with all new smog equipment and running in tip-top shape.
