Want this question answered?
wheel bearing, gearbox or wind noise Supercharger?
It may be the Idler pulley. I used to have a 96 Breeze with a 2.0L 4cyl that made a whining noise. I thought something might be seriously wrong, but then i discovered it was just the Idler pulley making noise. I changed it-- no more noise.
Whining noise near belts had pulleys adjusted any idea what is causing this
I have an after market fuel pump on my van the you can hear from inside and outside.
Its could be the turbo your hearing...
Could be the resonator
Gas Lid not tight is the reason my eng. Light keeps coming on
There could be many reasons why the Acura makes a high pitch whining noise. It could be that the brakes or the rotors are going out.
There could be many reasons, tell us the make, model, year of your vehicle and where and when the noise happens. 2000 chevy malibu and it sounds like it's coming from transmission. It starts after the car reaches about 30 mp and is constant
Hard to tell without hearing it. With engine running, open the hood and try to determine the area where the noise is coming from then repost info.
It may be low of lube or a bearing may be defective. Have it inspected by a professional.
Previas have a history of a whining noise coming from the catalytic converter. There is a bracket inside the converter that when loose or has came apart creates the whining noise during acceleration. It especially is very pronouced during high speeds in the freeway. You might be in for an expensive cat converter replacement.
