Question about 2004 Toyota Sienna
Vibrating plate-like sound coming from under the engine which seems only to happen when car is idling. I took it to the dealer. They apparently removed a heat sheild that was loose. It still makes a sound. In fact it's louder.
Maybe squeaking belts.Try a couple squirts of wd40 oil on pulley where belts meet.
