one time i had knocked off a vacum line behind the engine up by the fire wall i think going to the Map sensor.. you could check the one at the front passenger side runs across right by the water pump down to the pollution canister mine has pulled off there before. there is a line behind your glove box also that connects to the heater control, maybe it got hung up on the back of the glove compartment and knocked off it joins together..
the lines off the throttle body run underneath the top intake, 1 goes to the fuel pressure thingy lol, and T's off and runs across to the passenger side to the canister.. the other runs back to the MAP sensor and T's off into the wire harness and comes in by the ECM and joins up to the line going to the heater control there. . if you follow the lines off the throttle body you will find where they all lead to.

circled in red is the line going to the canister... it can easily pull apart there, especially if your engine mounts are not great.
If you look below the throttle body at the 1st line that runs down it T's into the fuel pressure thingy the other line is the canister, and one comes out the back to the firewall to the map sensor then runs inside the wire harness and in under the glove box to the heater control, not many lines to trace....
