i get like a whistling noise from 1k rpm to 3k rpm....it might go higher but i cant hear it cuz the intake really roars after 3k.....when i put my a/c on im pretty sure it gets worse....im thinkin its a vacuum line...any ideas...this isnt the whine from the timing belt i was talkin bout b4...that noise is gone.....this is more of a whistle....really aggrevating....any suggestions???
