    My car has recently had a lot of problems and I'm ready to drive it off a cliff. It has developed a new rattling noise that only happens sometimes. It doesn't get faster when the RPM's go up in neutral and its extremely loud. If it was the supercharger coupler, wouldn't the rattle get faster as the RPM's rose? What else could cause this rattle and only after the car has been running for a while?
