What you need to check is all the vacuum line under the hood. Just follow them from one end to the other look for cracked, broken or disconnected hoses.
The leak could also be from the intake or the air duct hose from the air filter. Also listen for a HISSING sound it should lead you to it.
It can take time to find but usually with a large leak it should take to long.
