Remove the gas cap and re-install it making sure that you hear it click several times. What your evap leak could be is the gas cap allowing gas fumes to escape. All it takes is a .040 leak to turn on the engine light. If it persists you'll have to have the emission system smoke tested. What happens is the system is literally filled with smoke and the leak will be found by where the smoke comes from.
