Before you change your cap, look at the seal and make sure it is intact and not cracked. Also look at the filler neck and make sure there isn't any rust on it. Also, a little bit of vaseline on the seal and filler neck will seal it enough to test for a week or two. The evap leak test won't run with a full tank of gas, It has to be between 3/4 and 1/4. If the code comes back after vaselining the filler neck and cap then you probably have a leak somewhere else.
