Failed emmisions, What could i do?

Rynb15 · Apr 15, 2006

I went to get the emmisions done today and it failed. It passed everything but the hydrocarbons. It read a 2.66 and it should be .80. Is there something i could by or do for a temp fix on this? Also my check engine light flashes everynow and then. Was told it could be o2 sensors. Any help would be great. I just want to get plates for this car. Im tired of swapping plates everytime i want to drive it. thanks

when i lived in arizona i had my car and had to do emissions. It had the B cam it which is not an emissions cam. Any ways first time there i hit a 36.12 and it was suppossed to be no higher than 12.00 for hydrocarbons. So i went to home depot bought 3 gallons of denatured alcohol ran my gas tank down to like an 1/8 of a tank and dumped the 3 gallons of denatured alcohol in. went back to the sniffer and put out a 12.04 for hydrocarbons. So just try denatured alcohol it should do the trick.

I had close to the same readings and I had to replace my OEM cats to get my car to pass.
The old cats only had 185K on them.. so I didn't feel that bad about replacing them to pass the emoission test.
Not to say that that is your problem but it's something sooner or later you'll need to address.

I had no cats on my car and i brought my levels down that far with a non emissions cam.
