Many of times it is the canister. 15 minute job and there is a revised part available from gm. Old style has a round cylinder canister and the revised is more of a flat box. It can be reached from the driver side wheel well under the filler door. Also keep in mind that aftermarket gas caps are more **** than the mg ones. Get a gm cap if you don't already have one, and if the code comes back do the canister. 9 out of 10 times it's one of those two things. Don't wast $ on a smoke test.
