Whistling "Ultimate Driving Machine" with an FM radio that goes in and out..
Does anyone know what's going on with the car? I bought it used, and when I intially start driving, it whistles.

And when I am listening to the FM radio, it goes in and out.

Any suggestions?

Alternator?

I was told once that when alternator is going you might get "whisle in radio"
It might have something to do with alternator brushes making electic interference
