I'm looking for a good diagram for the vacuum lines and don't see one. Besides the one on the hood of the car, is there another one?

More info.
When I check the idle with the car being cold the idle is ok, just rumbling, however when the car temp heats up, it goes high. I can't find a leak in the vacuum system unless the leak is at the vac line that runs from the solenoid to the canister, and the canister is in the back of the car. I did a ohms/resistance check of the IAC valve and it checks good unless the valve is just plain worn out.

There should be the vaccum source from the engine and another hose that goes back to the canister.
