Hello Mr.Scotty

So today I went to my car and turned it on. It sounded perfectly fine when it was on, no noise was being made at that time. Then when I started driving and started accelerating on the gas there was a hissing sound being made. And this happens every time I accelerate. I have a Mazda Tribute 2003. Could you possibly have an answer by any chance. I hope to hear back.

do this video to find the noise source https://www.youtube.com/watch?v=pqh1oH8mEqY
