http://www.youtube.com/watch?v=DNj4jw0wjyU&feature=channel_video_title Watch the video and help me determine what this knocking noise is. It COULD be an exhaust leak, but I'm not sure. The other noise, is coming from ehhh, behind the motor. I was thinking it could have something to do with the torque converter or the flywheel, ect, but again, I'm not sure. Any help would be awesome. Thanks guys!
