Thought this was discussed once, but can't find a reference. I get a chain-like rattle under the engine compartment of my 02 when I initially start the car. Sounds much like loose exhaust shield rattle, but I checked the shield out and it is tight. Does not do it consistently if car is restarted within a few minutes. Dealer has checked for loose things around my Injen air induction and exhaust system with no luck. Have some concern that it could be clutch or engine related, but don't seem to have any performance problems. Wondered if anyone else had any similar problems and what they found if they did. Would like to find it if it is mechanical before it gets more serious than a rattle. Dealer is willing, but unable to find it at this point. Thanks.
