There are many small hoses on the engine, they dry and leak, they break, they fall off or become disconnected. Look at them all very closely. My ears suck and I don't hear as well as I would like but listen for any sucking sounds around the engine.
Check the coolant and make sure it is full. Then with the car good and warm, crack open a bleeder and see if the bleeder lets out air or steam. GEt the air out of the system.
You can take off the Idle Air Control valve and clean it completely.
