Strange Noises...

[nfs13b]

Hey All,

 

Lately I have noticed some weird noises on my 2003 6litre 2500HD...

 

Of a morning when I start the car and accelerate down the road sometimes while I am accelerating I can hear like a whizzing noise which sounds like its coming from the radio..... Now I have seen this in some older cars where its radio interference etc... but this has only just started in this car and I havent changed anything lately...

 

Also there are other times while I am driving and accelerating or under some load and I can hear quick ticking/flicking sound that seems to be coming from either the dash or the engine bay area straight in front of the drivers area (My steering wheel is on the right hand side)

I would say the sound almost sounds like a gauge going haywire in the dash, but none of them appear to be doing anything.... if I take my foot off the accelerator and back on again it seems to stop....

 

Its not the Injectors as I am running on LPG and the LPG injectors have a different ticking sound... lol

 

Thanks

Lee
