ITs your evap system, first check you gas cap and make sure its on, if you fill you tank up iwth gas when the car is running then that is you rproblem just wait and it will go off. second
the evap canister is plugged and not working, if you take your drivers side rear wheel well off you can see this canister take it off and clean it and the lines going to it b/c carbon usally biulds up and cloges the lines. Lastly is the the purge solenoid is shot this is on the front of the engine right near your fuel injectors it has a vac line going to it, the black one ontop the the engine follow it to the front of the engine. First check the gas gap, then check the canister and if that doesn't work go to gm and buy the canister and the pruge selinod it will only cost you about 40 bucks. Good luck and Welcome to the forum.
