I have a 1992 Sc300 with a 1jzgte swap. I went to take my emissions test and failed on the hc portion or hydrocarbon level. First test was 433 of 400 allowed and then I went to Autozone and bought a bottle of CRC Guaranteed to pass emissions solution and followed the directions and went in for my test and failed with a 465 of 400 on hydrocarbons... So worse than the first test.

My co numbers passed on both tests. They are doing an idle test where I have to rest at idle for a few mins then between 2250 and 2750 rpm for a few minutes and repeats over then done. They are using the sniffers in my tailpipes.

My tabs expire at the end of May (registration actually says it expired on the 18th of may) but my sticker is a 5 (may) ...lol SO any help is greatly appreciated. She is my daily driver and I need her to get to work.

I am in Washington if that helps.

Thanks!
