This is the second ford I've owned and have a few problems with it . I replaced the plugs and one coil pack but I can't get the coils to stay seated . I don't have anything to screw them down to . There not a place for it . I need some help so I can sell it .

 

5.4's never came with coil packs so no surprise there isnt a mount for them. Sometimes a Coil on plug mount gets broken off. If it is completely broken off there really isnt a fix except replacing the manifold.
