My check engine light went off on my 2005 with 100k miles. I had them run it for codes at Auto Zone and it came up as a "large vacuum leak". What do I need to check or do?

i would assume vac leak is under the hood, but gas cap most likely? theres not enought vacuum in the tank cuz of the cap and it throws a code? give it a shot

im betting its an EVAP leak from the gas cap. but without the actual code it would be hard to confirm.
