im throwing this code, and i have searched and searched, but everyone is saying gas cap, gas hoses and such, but i cant smell any gas, and my gas lid is tight, so does anyone have any ideas?

 

Evaporative emissions control system leak (large)

what have you done(mods) to the car recently?

and tighten your gas cap

 

the only mod that it has is the cat-back exhaust, and that was like a year ago, so i dunno if that would throw the code or not....and when i give it fuel it sounds like there is sucking coming from the intake area somewhere, and i dont have a CAI, so i dunno if that is normal or not.
