I have a 1999 GLS, and it seems when the engine is warm (After driving for a while), I'll get a strange resonanace from the driver's side while accelerating. Almost like the airbox is vibrating, or there is something else making the noise. It only happens when the vehicle is warm. It also tends to get louder the more I open the throttle. Now, I did notice that my airbox mounts are broken, so it could be that, but I was wondering if anyone else has had this problem...

Thanks!

The heat shield could be cracked. I noticed that when mine was cracked that the noise was more noticeable after I drove for a little while.
:dunno:

The heat sheild for the Cat, or Muffler, or where, if I may ask?

How is your ac doing? Is it working fine, or when you are not moving is it just blowing hot air, and then when you speed up it goes back to cold?

 

[TeddyTiger]

The AC is okay, though the bearings on the Compressor are shot.

Very well COULD BE that airbox bangin' around in there... the high the revs the more air you're suckin' through it and the more turbulance you're going to have....

Tighten it down; or ... go ghetto to test it and jam a rag or 3 in there to keep it from moving. But make sure it's TIGHT, don't want them to come loose in your engine bay especially while revin'... might wanna test it in Neutral before you pull out as well.

This sounds like the same noise I'm having with my 1999 NB. I'm a dumb girl too so could you be more simplistic in your explanation of what to do about it?

It was the heat shield for me

I had the same problem one month ago. When we jacked the car to mount the snow tires, the heat shield was cracked.
