Emissions,emissions,emissions

Everything has passed on my FC but hydrocarbons. What exactly is the problem there? I have done a full tune up and it runs like a champ only 48000 original miles car sat for 14 years before I got a hold of it. Drove it for a week at high RPMs (highway) and then went to test it, hydrocarbons was off the charts I need some expert advice.
