We have the same problem. It's an air pocket in the cooling system. The cause can be anywhere from not filling the system all the way or most likely a leak has developed and air has entered into the system as the coolnt level has dropped. The coolant light goes off and on as the air pocket moves around.
Our Montana has a leaky intake gasket, which is the source of the problem. A very common problem with the 3.4. It should go for another 100K plus though, once it is repaired.

The buzz could be the fuel pump in the gas tank.
If it will run with the throttle open it could have an issue with the idle speed control valve or a dirty throttle body.
The computer controls idle speed by how much air enters the intake thru the valve.
