Hi all,

I seem to be getting a faint whistling noise (not a buzz or hum) when im pressing the accellerator. It only happens every now and again and only since the cold snap...any ideas?

Hi,

Have a look from the air scoop that goes into the air box and follow the pipe back to where it goes into the induction side of the engine,if there is any leaks as you put your foot door on the throttle the engine sucks in more air from the induction and that could be causing the whistling sounds under load.

Cheers..

Chips.
