I have a buzzing at Idle that's really making me go crazy. It only comes on at Idle. If I add a little gas and the rpm moves away from Idle, the buzzing stops. The buzzing sounds like it's coming from the driver side. What's causing this buzzing?

 

Check the throttle cable to make sure it is not resting on the alt.

 

check for anything that could be resting on anything else near the engine...it could be rattleing and not buzzing
