I hope I can explain this right. If I am driving at any speed, if I slightly press on the gas I hear a slight whistling sound. Like something is sucking air. It's not loud or anything and maybe it's normal since before I always had the stereo on and maybe didn't notice it. I think I would have. Does this sound normal. I went back through my install and made sure all the hoses and clamps are on correctly and tight. The vaccum line and crankcase breather line are on tight. Any ideas?
