I think i may have a bad timing chain tensioner on my 1997 cobra. It makes this horrible rattle at the first start up of the day then slowly dies down. However, it rattles whenever its at 2000 rpm- 2500 rpm. It doesnt rattle anytime above that powerband or below it. Does anyone have a video clip or sound clip of a bad timing chain tensioner for these cars? Id like to confirm the noise before i shell out the cash for an expensive job like this.
