Did you hear that quick, short BUZZ?
 

I have the 7 speed auto. Has anyone heard a buzzing sound that seems to come from the top of the engine, back of the dash area?

When I start my Z, sometimes, not every time, I hear a short buzz right after the gauges have set themselves, kind of part of the "boot up" process. I also have heard it when accelerating to around 8000 rpm's, just as it gets there. Again, only once in a while.

Sorry man, I have the auto but have never heard it.

Fuel pump?

I definitely wouldn't describe that as a buzzing ... but we all hear things differently.

Truth, more of a whining.

Yeah, that's a good word. An electric whining.

Geeze! After all I heard about that awful whining sound, glad it's NOT that!!!

Nope! It's about a half second buzz. Maybe there's a bee in there and when I start the engine I wake him up!

Now that I have around 4000 miles on my Z and everything's had time to "wear in," it's probably some little part on the engine that is showing it's personality.

As I say, not every time, in fact, hasn't done it in a few days.

I'm more curious that anything else. No big deal.

7k On the clock, and no issues with noises.

Have you noticed if it does it when you turn on the car, but not actually start the engine?

I have a manual, i have heard it or something similar, i believe it is in the dash area or thats where mine seems to be coming from...

i am in the process of tracking it down... and no, i haven't taken apart the dash before.

Can't say I've ever really noticed it

2009 Z? This may be the infamous ECU whine.

does it do it when you accelerate, and worse when the a/c is on? my plastic shield between the wiper arms and windshield vibrated like you describe, but also at 2.5-3k rpms. I put thin sheets of foam under the shield and its gone completely. took me forever to find it, but i knocked it out as well as my strut bar vibration and hatch rattle all in one night!

8K?(!) I would think the engine may make some sort of strange "noises" when revving that high.:bowrofl:
