Hydro Carbons are usally from an engine missfire. It may be that it is such a sligh miss that you cannot feel it. What is your timing set at? I would try setting it at 2* advanced and see what that does for you.

Does it have a vacuum leak? If it was that bad it should have thrown a code. That being said the first thing I do with a vehicle that fails emissions is to replace the o2 sensor. o2 sensors start wearing out the day they are put in. Generally I like to replace mine once a year though I know that is a bit of overkill. It does make sure the system is running topnotch. keep in mind my vehicle only has one o2 sensor.
