My car is a 2017 Mustang GT with GT350 intake and throttle body. I put my GoPro in my CAI box to record some sound and realized it could be useful for diagnosing this issue. I’ve had the car for nearly a year now, and I’ve always noticed this sound once it hits a high pitch (it has gotten worse in the last few months as well). The only things I figure it could be are a vacuum leak or the VVT solenoids. I’m leaning towards a vacuum leak after hearing it inside the engine bay. What are your thoughts?
