I have noticed this a while ago When I drive by streets with trees along side or through a bridge my car makes a noise that sounds like scissors opening and closing real fast, if that makes since. This can also be heard at idle outside the car. I don't really know what to make of it. I changed the oil when it was time and still made the noise, there is no noticable lose in power either. I don't fear anything from it, I just want to make sure it is nothing seriouse. Sorry for the spelling errors, I'm not to good with spelling.

HAHA, I know exactly what your talking about. I have the same problem. I think the reason mine does this is because I removed all the under engine panels so now the noise from the belts is making that noise

 

yes same thing happens to me when im the only car on the road it sounds like a fast rattling nose. i too dont have no under panels

 

I still have my underpanels but I took off my exhaust heat shield, that could be it. Thanks for the responses.
