Any number of problems can contribute to excessive unburned fuel in the exhaust. (elevated Hydrocarbons just means that the fuel didn't burn completely)
Check the air filter first, that's a common problem. Also, how long since a tune-up? Once the spark performance starts to diminish you'll see elevated HC.
Also, if your vehicle has an oxygen sensor it could be worn out, but usually that would be detected by a diagnostic scan.
These are just some thoughts on the subject. .

Why do the lines converge at high frequencies in the emission spectrum?
In an emission spectrum, lines converge at high frequencies due to the increased energy separation between quantized energy levels in atoms or molecules. As frequency increases, the energy levels become closer together, leading to more closely spaced spectral lines. Additionally, the broadening effects from factors like temperature and pressure can further cause these lines to merge, creating a convergence effect at high frequencies. This phenomenon reflects the underlying quantum mechanical properties of the particles involved.
