Recently just bought this car a couple of days ago and now I’m hearing a whistling noise every time I accelerate on the highway. What could it be?

That's a good one, thanks for the video. Is the noise coming from inside the car or under the hood? It must be a vacuum leak the best I can tell, or it could be the throttle pedal position sensor. Does it make noise with the engine off if you depress the throttle pedal? If not, we need to follow the noise to pinpoint where it is coming from. If the throttle pedal makes the noise without the engine running here is how to change out the part mentioned. Check out the images (below). Please let us know what you find. We are interested to see what it is.
