You have a EVAP code for a small leak. It could be the cap, but rarely do they go bad. What I suggest is this. Take the car to the shop and have the "Fog" the system. What they will do is actually pressurize (like 1 PSI) the evap system with a fog. Where the leak is, the fog will leak out. That is the easiest way to find it. Otherwise, you could be looking for a year and still not find it.

Let me know if it helps.
