I was gonna say maybe a small vacuum leak. I could be wrong, but idk. Go just trace out all your vacuum lines with some soapy water and rub on your lines. If you see any bubbles forming, you found your leak.

Does the car idle fine?

are you running airbox lid off/aftermarket intake?

All parts on my s2000 are stock.I will have to check the cars vac. hoses for leaks.The car runs and idles perfectly.Thanks for your comments guys.

Whistling sound is air moving rapidly inside your intake as you accelerate, throttle body opens the butterfly and more air comes in rapidly. It is normal. Soap bubbles will not find a vacuum leak...
