Scan for codes, check fuel pressure with a gauge auto parts rent it, and check for a vacuum leak.

It cold be the solenoid on the evap canister leaking. But should be smoke tested. If you check what I said in reply should fix it. Also clean your throttle plate on both sides with choke cleaner and iac hole. See pic for causes and gas cap must click three times after a gas fill up
