Underhood rattle? 4th gen TA
 

Hey guys, I just landed my 2000 firebird and I'm noticing that there's a strange rattle coming from under the hood that gets louder as I raise the RPM's, however it's not loud enough to overpower the sound of the motor, and at idle is too quiet to pinpoint. The only time I can hear it is after letting off the throttle. Anyone know anything about something like this? It's the LS1 motor.

Thanks!
