Is it a vacuum leak?
I dunno guys, but my max makes an "airy noise" while the car is running with the hood open. I rolled up a long piece of paper and used it like a stethescope and found that the noise seems to be coming from the hoses around the pcv valve, -somewhere in that area at least. I mean, should the engine make SOME whishing sound? When I turn the car off for the last half second you here a final louder swish typr sound as the moter dies. It is a quick swishing sound. I don't have an intake- The car is stock. I am noiw worruiesd that the car is sucking in dirty air from somewhere. I know I am a little paranoid with my max but I think this may be a somethign tobe concerned about? Could there be some hoses that I need to look at UNDER the car? everything up top looks perfect.

You will probably need to spray some ether near the hoses to see if the engine runs at a higher rpm. If it does that, you have located a possible leak source. Don't use too much ether though. Just do it in very short bursts.
