Odd squeal coming from my car
 

I just noticed an odd squeal today, i had assumed it was my brakes but when i listened closely it wasnt, it stops when i accelerate, and squeal about 80% of the time while coasting and stopped idling, the volume of the coasting varies in that while accelerate it stops and then when i let go of the gass will either not squeal, squeal a little or squeal alot, and it semms to squeal more i hit a bump, any idea what it is?

How old are your brake pads? Is the squealer tab rubbing on the rotor?

another thought: Wheel hub/bearings?

i said it still sqeuals while i am stopped, how wud the wheels be making it when they not spinning

:D Hello NERV, I just re-read you post, and noticed your statement "and idling."

The problem is, you have a vacuum leak somewhere. If you haven't found it already, you will want to spend some time checking around under the hood with the engine idling. Sometimes a piece of small hose (maybe a 3 foot long piece of vacuum or fuel hose) will aid in finding it. (used as a sort of stethoscope/listening device)

Just be careful messing around under the hood with the engine running :!:
Those serpentine belts can be VERY DESTRUCTIVE :evil: to fingers, hands, etc.
:!: BE CAREFUL.

Sorry about that Nerv. I had trouble reading your first post. Either the vacuum leak or a belt.

yes deefinitely be careful with the whole pully end of the engine!

I was poking around my uncle's regal (3800 series 1) and i STUPIDLY put my hand down "wherever" and "Wherever" happeend to be the alternator pulley's fan!
I thank GOD that somehow it just sorta bit my hand and spit it out because i know for CERTAIN that a hand or fingers easily get stuck in that alt. pulley and I don't th ink i have to tell you that an engine is MORE MORE MORE MORE MORE than capable of destroying measily, weak bone!

With that out of the way, I bet it is a vacuum leak. I used to hear an electronic "wine' come out of my engine somewhere which was audible while i was in the car driving! I don't know what it was but (for the record my uncle's buick regal had it too). I think with time it has gone away (but i have replaced most vacuum lines since then so it might have been that!) but let me just say that my brother's ahem.. mitsu eclipse :roll: ... makes it too and he knows for sure its coming from his fuel pump, so i just wanted to give you that idea to listen for. (maybe its coming from towards the back).

i cant seem to be able to egt under the hood to test it, ive driven aorund my neighboorhood a few times to get the squeal to start and when it does i park and open the hood but by the time i get it open it has stopped, any suggestions or should i just bring it to a mechanic and let them figure it out?

Could be a pulley?? Maybe the Harmonic Balancer..? Pow Ster Pump.. Alt... A/C?

Is the hood rattling?

Sidenote: Gearheads, maybe TC has problems under light load?
