Hi all I just bought a 2000 Nissan Pathfinder le 3.3l v6 it had to have a crank shaft sensor and a distributor it had sat for about a year before these things were put in now there is a banging noise and it is like something is loose and swinging back and forth it hits the floor board of the front seats you can feel it with your feet I was told it was a loose heat shield but got under it today and couldn't find anything loose that could be making it do that anyone have any ideas
