Whistle type sound when accelerating

[computone]

Hi,

I'm not very car literate, so not sure on the best terminology to use, but I have a VZ Berlina Wagon, and about 6-9 months ago, it started to randomly generate a whistling / whining type sound when driving and accelerating around 2000rpm.

Lately it's doing it all the time, and I found out today it also does it when idle, but around 3000rpm.

When driving (accelerating on 2000rpm) it's pretty constant. As soon as you take your foot off the accelerator, it stops. As soon as you put it back on and get to around 2000rpm, it's back.

When idle (in neutral or park), and accelerating around 3000rpm, the sound is back, however it comes and goes, consistently, on, off, on, off etc.

From having someone else do it when I was standing outside the car, it sounded like it was coming from underneath the body somewhere, more so than in the engine bay, but I could be wrong.

I'm thinking of taking it to the local Holden dealer to see if they can locate it, but if anyone here has any ideas in the meantime, it'd be much appreciated.

Thanks in advance.

Check your air hoses under the bonnet that they are all secure also check and see that they are not cracked or have worn. Anyway a good way to start your elimination process

maybe u have a tuuurbbbooo FULLY SICK

[impulsive]

check your extractors, for cracks and holes, i had a crack in mine causing a wierd noise, not much of a whistle but a noise.. or check your exhaust for faults..

It's because of your Air con, turn off the air con and you wont hear a thing. Have it full blast and it will "whistle" away. VZs have a natoriously loud air con whistle.

or maybe its a diesel?

Nope i think he ran over a lolypop lady!

[f1tzy]

Have you put speakers + amp in your car?

[Commydoor]

maybe a blocked muffler....then again maybe im full of s**t lol...

check for exhaust leaks, look along the pipes, particularly in the pipe flanges(joins) and around the exhaust manifold, look for cracks, if its been doing it for a while, black carbon build up might have run out with condensation so look for black trails

mate i have the same noise on my car, not sure where it is from and would love to know the cause...

[andyman]

i also had a whistle from by throttle body to inlet manifold gasket whistle, it was my own fault but, i cleaned the t/b, and the gasket got a slight tear in it, fixed it with a bit of gasket goo

I've herd the same only herd to a couple of times when had been doing open road driving....

Its probly the air con. try driving with the aircon on and off and see if you hear a differance. its what happens with mine.

yeh dude same here... so is this a normal thing?
its annoying... but if its normal my fix will be to just keep the stereo up loud lol.

[squawk]

think mine is interference when playing my ipod through the radio tuner

[STRIKE]

Yeah i think its normal but not sure what causes it. My mates Vectra does it but my old VX didn't must be just certain cars.

try a late model subaru, that will change your perspective of what a loud air compressor sounds like, its louder than the engine at idle

[svsex]

have a look at ur power steering fluid, if its near empty it wines likes crazy

maybe a midget is holding onto the bottom of your car and whenever you accelerate is whistleling and whining.





lol sorry i felt it was totally relevant




wow that was a low joke

[Ewok]

Hahaha I was going to ask if he'd bought me old battery..... Supercharger sounds included.....

Running on LPG my car backfires occasionally and causes a small air hose under the air inlet pipe to blow off, this causes a whistle sound that is most obvious when travelling up hill, you just need to take the decorative motor cover off and then you will the hose under the air intake pipe just above the inlet manifold, I'm not sure if I have the terms right but it was easy to see, it is on the passenger side of the motor around 10cm from the centre of the motor
