Intake manifold could be air leaking near a gasket......I was working on an Accord.....replaced the upper intake manifold.....there was a high pitch sound coming from the engine afterwards.....sounded almost like a squeak or a whistle......I checked all the intake bolts and one of them was loose. I tightened it half a turn and the noise stopped. I've heard similar sounds coming from the "quick-connect" vacuum lines on fords..

Spray carb cleaner around the engine to see if there is a vac leak/change in idle....

Thanks guys, You where right! was having a problem installing the intake manifold, was fighting it and cut the gasket a little on the left side. To be sure I used some carb cleaner around it like tech II was saying and right on the left side there was a difference after spraying the cleaner there. would have never guess it was that. Wow. check out the links below>

Glad you got it fixed, sounds a lot better now, it was so loud at first you almost could not hear the motor run...
