What I hear is definately not the alternator. It's an intake sound. It is coming from either the intake itself, or the throttle body. That's why I think it has something to do with the idle bypass system. Once the car is warmed up it quits, and it happens only at light throttle or idle in my case.huskerGTO said:alternator
That sounds like a diode going in your alternator. You should go to the dealer and get it checked out.huskerGTO said:Hmm, I tried turning the light switches to check if the amps from the lights made any difference, and YEP! the whistles changed pitches..
I dunno what to tell ya though, maybe check to make sure everything is sealed right, airbox, intake manifold, etc
