I smogged my car today and failed due to high HC levels, everything else passed with flying colors. I changed my headers back to stock as well as my ecu and intake. Can anyone give me an idea of what may be causing this problem?? I had a high flow cat installed, maybe its not enough to do the job? everything was stock on the car except the exhaust and cams.

I'd guess the hi-flo cat may be to blame, cams probably don't help though. Have any of you CA guys tried that CRC Guaranteed to Pass fuel additive? I have no idea if it works or not but it might be worth a try if it saves you the trouble of swapping everything back to stock.
