I don't know much about cars so I'm looking for some advice. I have a 95 GT 5.0 and today when I started it up it was making a goose type honking noise - like a sick animal. From doing a little internet research it sounds like a "CCV" problem but I don't really know what this means. Can anyone advise how much something like this will cost to repair and if it's safe to drive it like this? Thank you!!
