I have a '97 Explorer with the 4.0 OHV engine. Whenever I have the accelerator pedal down about 1/4 of the way, a high-pitched whistling noise comes from the engine (sounds like air coming out a tiny hole or something.) It does it no matter what gear the car is in. The X runs fine, however. Any one have any idea what the whistle is?
