My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
In allot of cases this type of noise here is created by a vacuum leak in the engine area.If you have not had the engine checked over for any vacuum leaks this needs done.If one is found it will need to be corrected to resolve this issue.A leaking vacuum hose or the inlet from the engine air filter being loose can cause this here.
