I have a vacuum line missing on the top of intake its a 98 explorer 4.0 sohc i dont know where it goes

 

Welcome to the forum!

You didn't give us much to go on here. Any chance you could upload a photo to a photo sharing site and link to it here? Does your Explorer happen to still have a vacuum diagram sticker under the hood which might give you an idea which line it is and where it should go?
