its almost a hissing sound, it only comes up in low gears(1st 2nd and 3rd sometimes). its not loud at all but i can just barely hear it under my engine sound. it almost sounds like a turbo lol. but once again its not too loud you have to kind of pay attention and listen to hear it. im thinking its coming from my tranny or engine because its coming from the engine bay, i did just put in an AEM V2 intake in my car and the intake has a nipple in it where a sensor is supposed to go that my car doesnt have, i have plugged it up with a rubber peice hat i had to cut myself to fit, so i was thinking it was sucking air through the hole around the ruber peice, but thats just a guess.

ALSO, when my windows are up, and my stereo is on there is something that rattles like crazy right under my drivers side window towards the front of the door, im thinking something came loose but im not sure.

thanks in advance
