Arrgh. I spent another .5 hour today bent over the engine, listening in vain for a whistle that is both nowhere and everywhere. Using a stethoscope (long screwdriver) I've deduced that the whistle can't be found. I tried wetting the belts; no change. I tried opening up the airbox; no change. I did notice that it's not tied directly to the throttle position... If you blip the throttle really fast, it'll whistle a fraction of a second later than you moved the throttle, more in line with the increase in rpms of the engine... Does that ring any bells with anyone? Thanks, Miles

Hi All- I've got a whistle in my wagon... It's only whistles when the motor is very lightly loaded. If the AC isn't engaged, it will not whistle at idle, but when the AC engages, or you're cruising on a flat road at 30-40mph (2-5% throttle maybe?) it'll whistle. Open the throttle past 5% ish, and it goes away. The whistle doesn't seem to be tied to speed, gear (AT), weather, and hasn't changed in the past two years... It does seem to be coming from the intake manifold area of the car (no gross intake leaks, checked by spraying carb cleaner everywhere - no; it didn't cach on fire either). Anybody have a clue as to what this could be? Thanks, Miles
