It is possible that you were hearing the frequency valve doing its thing. It has a definite buzzing sound. If it was more of a hiss than a buzz, perhaps it was your mode switch? Without more information, it's kind of difficult to propose anything else. Let us know if you can better locate the area where the sound is coming from. The List may be able to give better advice then.

The best way to describe it : you know the "radio fuzz" sound you get when you change radio stations with a turn knob radio dial? The imcomprehendable "bzzzZZzzzZzz" you get with turning the radio dial around, or when your TV shows nothing but "snow"? That's exactly the noise I was hearing. It wasn't very loud at all, and it went away after about 5 seconds. It did it one more time on the way home. When it happened this second time, I hit the accelerator; it had no effect on the sound. There didn't seem to be any direct correlation between the accelerator and this new sound. It didn't sound "rotational"; the sound didn't seem to run in consistant cycles. I parked the car, put it in park, and let it idle. Nothing happened. Hit the accelerator while in park - no "radio fuzz" sound. > > To say the least, very unusual. I had to go to work immediately after I parked the car, so I haven't had much time to really diagnose the sound or its origins. Any ideas anyone? >
