check your timing... i think high HC is timing related, my 323 gt failed big time cause my timing was way to retarded...

I'm failing what your passing and your failing what i'm passing

Edit: Did you change your oil before going?

Thank god for no emissions here! My car would totally fail.

Pour in a can of "Guaranteed to Pass".

advance the timing, it will bring up nox a little but but cut down the hc and co
