well if you bought a good gas cap and the right one you need to check for a leak at the evaporative lines check the pcv valve and for any vaccum leaks if that is not it you could have a bad evap vent selonoid or bad charcoal canister. it is a simple diagnostic if you had a scanner and a smoke machine.
