Why does my Car Idle Rough?

Your Car may idle rough for a few reasons. The first reason would be it needs a tune up. The second reason would be there is a vacuum leak under the hood somewhere. Listen for a loud sucking sound around the top of the motor for that one. The final reason is an exhaust leak as a hole in the pipe or muffler will make the vehicle run rough.
