Hi All
I have a 2003 UK 350Z. I have a problem with a strange noise at idle.
I can only hear the noise when i am sitting the car.
The noise sounds like it is coming from the engine, its a flapping noise.
It is most noticable at idle, on my car about 700rpm and about 20psi on the gauge, flap flap, flap, flap, flap.......
The noise is consistent with rpm, as i slowly rev the engine the flapping speeds up.
It doesn't sound like a metalic sound more of a flap......sorry its difficult to describe.
When i open the bonnet i can't hear the noise everything sounds good, can only hear it when I'm sitting in the car.
I'm a bit concerned where the noise is coming from.
Has anyone come across this problem before if so i would greatly appreciate your help.
Thanks for your help.
