I have a slight clinging or rattling from my passenger side under the hood. I only hear it when the car is idling or at a complete stop any ideas on what it may be?

Also do you hurt anything driving your car with a bad rear sway bar bushing?

 

I fixed it. It was a wire that the fan was nicking. I noticed it when i had juice to the car but it was not running so it eliminated a lot of items that it could of been.
