Ssssssssssssssss
 

like they title says... so my car makes a ''slight'' hiss sound when i rev/give it gas.. ALMOST like if a turbo was spooling up. not trying to make it sound like its cool but thats the closest thing i could say it sounds like.. anyone els got this going on? and no its not a ''tik'' sound from DFI.

thanks!

intake leak?

So i checked for leaks and nothing.. then i opend the hood and had a friend rev it a bit and its coming from the belt area... then i looked UNDER the car where the belts are and its coming from UNDER the car. hmmmmm.

Test for a leak in the downpipe. Are you throwing any codes?

It's a normal sound, a lot of people have asked about it and we all came to the conclusion that it is the sound of air passing through the TB

Just saw your other post, maybe it's different since its coming from under the car. But same sound, like a turbo spooling

no codes or anything thank god lol and if others have said they have this to im sure it should be ok X)

and i have checked all points where air of any sort could escape and nothing. ill keep this updated if it gets worse or i find out why this is going on. thank you all for the help :D

Cause my exhaust leak sounds like a turbo spooling a little bit, that's why I threw that suggestion out

My brother was fixing an eclipse and it was making this sound too. Turns out its turboed lol

Had a friend with a 2.2 ecotec grand am that was making a hissing noise. Turned out to be the ac compressor. The pulley had seized, and was causing the noise.

Check exhaust mani. I had a car makin a noise like that(made me feel cool) trned out being a cracked mani
