Find the website that handles the particular faucet to get an idea of how to take it apart. It sounds like it needs un-clogging, or a decent cleaning of the innerds. Its not unusual for small particles to accumulate over time. Clean out the filter at the very end of the spout along with the spray head and the valve body.
unscrew the aerator on the end of the faucet and clean it off, the screen is probably clogged.
