2000 RPM / 2nd Gear / 20-30mpg - Whispy Air Sound

[lukeskywalker]

I can't for the life of me figure this out. Has ANYONE experienced something like this? It's bothering the crap out of me.

It sounds like the blowing out of a compressed hose, a high-ish frequency whispy blow. And it only happens at 2000-3000 rpm, around 2nd gear, 20-30 mpg with medium to full acceleration. Almost like a turbo, then goes away right after. It sounds like its coming from passenger side , cant tell if toward the front or back.

Any thoughts , I shall ask the universe to bless you.

Thanks a million.

Air box not clipped tight?

I get a similar sound ever since I went to the the TRD intake. I spent an hour or two chasing down any loose connections, and then saw at least a few other people saying the same thing after adding it, so I chalked it up to something the OEM resonator took out.

90% of the time a random whistling sound near the intake side is an air leak somewhere.

Here's an update to anyone lurking. Again 2014 4x4, you may experience something similar down the line.

Clues:
1.) Only happens when coldish, first 10 mins of driving.
2.) Only can hear when radio is off.
3.) Power steering fluid has been low, and a week of low-ish transmission fluid that has been topped off properly.
4.) Mainly occurs in 2nd gear ~ 2000-3000 rpm.
5.) Sound in real life is more like a phaser effect. Kicks in inconsistently and sporadically. It's not "always there".


This one, sound starts at 8secs:

at 4 and 7secs:
starts at 4s and 6s - YouTube

Thanks for anyone with thoughts!!


My hunch now is that it's either the power steering pump or transmission pump. I tried topping off power steering with lucas power steering leak stop to see if it does the trick. Ill post back again with updates.
