when i step on the gas i hear a whisling sound, what could be going on? i throw the car in neutral and i rev the engine and i hear the whistle...the harder i step on the gas the louder the whistle gets... it actually sounds like its coming from the back of my car...but im not sure...any possibilites here? thanks guys

 

You have a turbocharger and you don't know it. :P

*shrug*

 

maximus what mods do you have done?

 

does it sound gangster like your s/c or somthing? maybe like this... http://s3.yousendit.com/d.aspx?id=1E...03646637866211 , or maybe this? http://s11.yousendit.com/d.aspx?id=F...0453320392E9DD

Yeah i've heard this too... it's like a supercharger but much much much softer, for me. I can only hear it with the radio off and when I'm sitting in the back seat. I dunno what it is though, bleh.

 

nah it doesnt sound liek aturbo it sounds like a bozo the clown type of sound when someone slips on a banana peel in a cartoon, it sounds doofy....like i left a window open a crack while speeding....it sounds crappy....i have a cold air intake, strut bar, eibachs, those r my only performance mods...

 

its most likely your intake.

did you fabricate it yourself? my friend made his own custom CAI for his mustang and it started whistling because of a leak. make sure everything on your CAI is secure.

 

I know that after installing my intake, a nice whistling sound started coming through but definitely sounds like its coming from the front. Think its coming anywhere in the exhaust system?

 

Does it go WOOO WOOOOOO?

 

probably your intake

 

yeah it kind of does go "woo woo", should i just get a whole new intake, its been in there for 15,000 miles so far i think....

 

I get a slight whistling sound from my A/C when it's on. I believe it is just the fan.

 

anyone throught he has alternator noise through his radio?

 

Do you have a system in the back? cause my friend just got that fixed in his Galant... the person that custom made the box for him and wired the system f*cked up... everytime he'd accelerate you'd a hear a whistling sound... (needed to be rewired.. he ended up busting 1 sub)

 

It wouldn't hurt to jack up the front of the car and then get under it and feel for leaks. You could even have someone sit in the car and rev it, in and out of gear to see if that makes a difference.

 

I installed my injen intake and it whistles dixy when i hit the gas but soon as the rpms drop down it goes away i actually love the sound makes my car sound p i s s e d but thats just me lol

 

this one seems to be my problem, because it only happened after my audio guy rewired my system and adjusted my gaines, so just MAYBE thats it...i say maybe only because i just noticed it, i almost never drive with no music in my car...and the whistling sounds like its coming from the back of the car not the front....so i dont think it would be the intake, almost sounds like its in the back seat of the car...

 

hole, in the exhaust, before the muffler (even possibly in the muffler outer casing), is another possibility.

look for rusty areas that may have a small hole or corrosion areas thatwould leak air.

 

i get this same sound, its kinda like a winey, squeaky sound but it could be described as a whislign sound, its only happens to me when i press the gas between 1000-2000 rpm and also makes the sound when it drops from 2000-1000 rpm, and i dont have a system in it at all, what rpms are you getting your sound at??/

 

it could be a bad ground or alternator noise from a custom stereo install

 

you do not neccisarly have to have an aftermarket stereo at all to get alternator noise, when i first bought my max it had bad alternator noise, just ran a new ground to my factory radio and it went away..

 

well, i get it immediately, as soon as i step on the gas even a little bit i get it....explain this ground wire thing to me though, ive seen a wire hanging around before i dynomatted my rear seat, i tihnk it may have been from my system....its just laying there, might that contribute to the problem? thanks so much for the suggestions guys, keep em comin (pause)

 

what happens is sometimes grounds go bad .....or if u have a wire hanging and now it is touching metal u will hear a whistling because the current travels through the car and thats y u hear it....if u have a custom stereo u might just have grounded ur amp or deck in a bad spot but good enough for it to turn on and u heare alternator whine through speakers....also if u have an amp ur ground wire maybe too long .......it can be all sorts of stuff.....go back and check that wire u had hanging either get rid of it if u can or ground if to the chassis.....

 

I had this same problem and it was basically becuase my ground was too close to my speaker wires that were running from the back of my car... I moved the wire over to the other side of where they were and it went away.

 

they all whistle

 

thanks, im gonna try that, if it doesnt work...ill def be back

 

Hehe yea it took us a few days to figure out the whistling was coming from this kids system in the back.. as someone already posted there was a grounded wire... he had his system installed for free w/ free custom box but the guy that did it f*cked up :-/... being that it was free there isn't much he could do.. he took it to a pro though and got a box made half the size of the other and the problem fixed for like 250$ :-/..

i don't know much about systems, it's just this thread caught my eye before because as i stated my friend has the same problem.

ask admin to post this thread in the car audio section / go to a pro and have him check it out.

- good luck to you

 

it could be the A/C

 

Is one of your side mirrors cracked? Mine is and whistles like crazy. Damn people at walmart don't know how to drive.

 

well i checked it ou, and had my friend rev the engine while i looked for the sound, and it is coming from my system i believe...its by the rear deck, i guess ill take it back and see whats going on..thanks for the help, ill be back here to let u guys know how it went....

 

I had this same problem and it is the ground wire for my subs. It has actually happened twice. The first time I just tightened the ground. The second time I removed the bolt, sanded the area, and retightened with a lock washer. I have not had the problem since.

 

damn people at walmart don't know how to get VISAs instead of just crossingthe border.

 

i have 5spd no mods and have the same whistling sound, only when the car is in gear, in neutral it goes away. i asked a mechanic from firestone and he said that its normal for these types of cars with 5spd. so i stopped worrying about it.

 

well it happens now even when the car is idle i hear it a little, so as soon as i turn the key i start to hear it, which leads me to think its an electrical problem with my system somehow....

 

My injen makes a whistling sound also. Also when i shift into 2nd, it sometimes makes a slight blow-off sound... kinda weird

 

well it looks like it may be the subs, or something like that, i have four wires loose, just hanging in my trunk coming from my subs i believe, should i ground these without knowing what they are or what they do? and isnt that dangerous to just have wires hanging there? should i go back and shoot the guy that installed my system?
