Thanks for the reply. I have checked the underside for the rattle. Everything is nice and tight. One observation I did make, is, when holding the throttle around 900 rpm, I watch the tensioner pulley vibrate a little more than it should. It shudders during the same time the noise is being heard. I would assume that possibly the rattle is somewhat being caused by a worn damper for the tensioner pulley, or perhaps a worn tensioner. Before replacing the parts, I thought I would ask here, to see if anyone else has had, or heard of the rattle being caused by the tensioner or damper. The car also has somewhat of a rough feel to it during acceleration of 700-1100 rpm. If I knew the cause of that, perhaps the vibration and noise would cease. I would think the idle and acceleration should be smoother than it is.
