I have a 2005 cobalt ss supercharged. It has about 94k miles and ive noticed that when i give it gas it makes a weird noise. it almost sounds lik zzzzzzzzzzzzzzzzzz. It sounds like its coming from the passenger side but i dont know what it is!! I thought maybe it was a vacuum leak or an exhaust leak but i have no clue. PLease help

maybe an exhaust leak. when i had a leak at the header dp connection it always sounded like it was coming from the passenger side.

So i basically got a new header and downpipe and i love it now..but it stil makes that noise so idk maybe a intake manifold gasket?

could it be the alternator starting to whine? I havent ever had an alternator whine on me, so i'm not sure, but it sounds like a plausible cause.
