With the evap code, I would check all the vaccum lines first. It's the cheapest and easiest to try first. Also check if the gas cap is loose. If it's the gas cap, it will take a couple trips to clear on it's own.

**In reference to the lines, obviously you want to check for holes, but also look for severe dry cracking. Replace any lines that look doubtful.
