Rattle

Alright heres a tough one:

After installing my injen intake, i had a slight rattle sound around 1000, 1600, and 1900 rpm only. It sounded like it was coming from just behind my dash/gause cluster area. The sound is pretty deep, and also pretty aggressive, and it is definitely coming from the engine bay somewhere. After puttting my stock intake back on, it is worse (real significant at 1600 rpm). I checked everything to make sure it was tight (power sterring reservoir, intake filter box, etc). Any ideas?

Tim

I have the exact same problem, even with stock airbox. Something is ratting near the side driver side vent/behind the dash!
