Whistling through my Taco

[jdr3366]

I have a 17 TRD auto 95,000 miles. There is an occasional whistling sound coming from the engine (I think) when I accelerate between 30 and 45 mph. It only lasts for about 5 seconds.

Not every time I accelerate, and it can go away for a month and then come back. Ghosts?

Help.

Supercharger.

Does it happen only when the AC is used?

I have AC on all the time. I'll try without

Supercharger is fine. Had dealer check it.
