Hey there I have a 2003 F150 with the v6 engine and its got 165000 miles on it. Its been running lean on both banks and has the code P0456 and says "Evaporative Emission System leak detected (very small leak)". What should I be doing to get this fixed? Is this a major problem?

Smoke test will point out where the leak is coming from, if left unfixed, check engine light eventually, could turn into a bigger leak if left untouched.
