Default 98 SE, weird sucking/ whislting sound...

Recently bought this awesome 98 SE and noticed, during acceleration, I hear this sucking whislting sound coming from below. It progresses through the first two or three gears (auto), then seems to go away.

Any idea what it may be and if I need to worry about it?

From below?? Below where?

Could just be intake noise if you're really getting into it

Seems to be coming from the header area, perhaps the transmission.

And, if it'* a simple fix, how should I go about doing so?

Aftermarket turbo?? :shrug:

I'm sure you'd notice other problems if it was vacuum tube loose...hmm...

Could the tranny itself be making that sound? Seems too low for intake noise...

Definately no turbo. And, tranny is the first thing I thought of because the sound follows the rev of the gears/ engine. Odd sound.

Heheh, that turbo statement was a joke. :P

Is it a rushing air sound, or perhaps light scraping like a dry component?

if its making the sound while in park and you think it'* around that area.. easiest way to eliminate the theory about the intake is to simply remove the Accordian tubing from the TB and you'll hear the hissing kinda sound either louder or gone.. if it still is.. then you know it'* not from the intake and we can troubleshoot knowing it'* not the intake ( unless it'* a leak somewhere )

No, only during accelleration.

Can you reproduce the sound a lil while in park and pull on the Throttle linkages @ the TB to rev the engine ( burp the engine ) to see if it produces the noise you're refering to?
