    I have a '97 Ford Taurus, and my car is also making a whistling noise. I live in South Bend, IN, and lately it has been pretty cold and snowy. I'm wondering if this could have anything to do with it. I also noticed just tonight that it starts whistling right at 25 mph.

    PS. Does the '97 actually have a bypass valve? And is the noise I'm hearing mean that it's working?

    My wife has a 2005 Ford Taurus and it seems to have the same problem. It started whistling a couple months ago when the winter weather came (I live in Indy) so I guess it could have somthing to do with it (cold air making the sound??). I hope it is what you say it is (air bypass valve) and nothing more serious. The valve doesn't cost much (just about $50) and seems like an easy fix...

Engine is whistling loudly, and stops if i remove

I would have the converter checked for back pressure. if it is plugged it can cause excessive Engine pressure. if it is not plugged then you have excessive blow by or a malfunctioning PCV system it sounds like.

Sounds like a vacuum leak. Check all vacuum hoses on the intake, throttle body, etc. Sounds like one cracked or came off. Post back if you have any questions. Hope this helps.
