Subject:      buzzing noise
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

So...
I have this buzzing noise coming from my engine compartment.  It think
it's most noticeable at an idle, especially if your sitting in the back
seat.  If I had to say, it seems worse on the passenger side, but I'm
not sure about this.  When the engine speed increases, the noise doesn't
seem to change.   Makes me think it's electrical?  But it doesn't seem
like its the fuel pump (it's buzzing when I go near it but not nearly
this load), and I don't think it's the alternator either---when I open
the engine compartment, it's difficult to isolate the buzzing since the
engine noise overwhelms it.  With the compartment closed, the noise
comes through loud and clear.

Turning on headlights (increasing load on the battery) makes the buzzing
go down noticeably in pitch., at least at an idle (although I guess the
idle rate is decreasing slight in this case too...)

any ideas?

Thanks!
