Donations are not a requirement but they are appreciated. There is a very large amount of unanswered posts and very few moderators to help answer them. Donations get priority and we get to the rest when we can.
As far as your problem you say when it idles you don't hear anything? How about when you're driving put it in neutral and listen. Is it still there? Can you give me a general direction of where it might be coming from? Let me know.
