Mines did this was the rubber boot that connects to the Throttle Body; 18$ part from a dealer (mines was free caught it when purchasing) and not much work to replace, inspect for a post maf vacuum leak.
Was a high pitched whistle only on acceleration.
If you can have a buddy press the pedal while you're looking under the hood to pinpoint the noise area if its not as obvious as mine was.
