When I turn my key to ignition or start (not sure of the name, the click just before it starts, when all the dash lights come on) I get a loud buzzing from the posterior of the engine bay. This does not go away with time. I do not remember this with my 03. It is easily noticeable. Anyone else note this??

It does go away with one click back (is that acc? can't remember ).

Like a high pitched sound? Try stepping on the throttle a few times and observe the sound in your garage. Is that the sound you're talking about?

 

Yeap, sounds like the throttle position motor/sensor "seeking". If so, it's normal.

 

Yes, it is high pitched and does change with throttle position. Just dont remember it so pronounced on my 03. Thanks for the quick feedback

I think it is probably something to do with the fuel system (priming the pumps), unless it's REALLY loud it's probably normal. (Or the throttle as dave mentioned?)

 

Well you gotta duet in there, so it's going to be singing in harmony
