This might just be due to the cold but...

I went out to start the car the other day (in storage for the winter) and, after the engine warmed up to operating temp, I gave it a couple of quick shots... just to make myself feel better...

I heard a slight squeak/hiss when hitting the gas quickly and nothing when depressing slowly....

Probably nothing that a shot of WD-40 wouldn't cure but I found it interesting....

Is this normal? Does anyone elses car do this?

 

Yes they all to this. It is normal.

 

So does anyone know what the source is for this noise?

 

Its the throttle body. The flapper causes a whistle as air passes at a certain throttle positions. Next mod: make it louder!!!

Wooooooooo Woooooooooo
