Its more of a high pitch vacuum sound
A friend of mine just had the same problem and what he said it sounded like a vacuum leak. What he did was had the car running and sprayed carb cleaner with the little straw around the manifold. I at one point you hear the Engine change pitch while spraying, Then you have found your vacuum leak. I haven't done that yet on my car because of work, but today im doing that and vac conversion for brakes. I'll let you know what happened, Im also going to the tensioners and pulleys while im under the hood. So Thanx again for all the responses.
Its pretty cool to have the support from you guys!!
