Whenever I am driving my car there is always a small whistle, I replaced all vacuum lines, pcv valve, new tb gaskets and more. If I get on it hard it sounds like a loud sucking noise and the car gets loud but isnt moving at its full potential. If this helps, one bolt is stripped on my intake and isnt bolted down. All the others are bolted though. Also has a jumpy idle when the heat is on. Any help would be greatly appreciated, thanks.
