PSS/POSKY 777 merge

When I do an APP for an ILS landing, the plane behaves way differently. When it catches the glideslop the throttles start moving forward and backwards trying to keep the speed the same, this infact then keeps making the plane bob up and down to try and keep the altitude.I know there have been many other posts for this, but does anyone else know how to make a better merge that lets the APP and ILS easier? Everything else works fine, climb, cruise, takeoff, etc....just when gear is down and ILS is on.I've seen this thread : http://forums1.avsim.net/index.php?showtopic=232055 but does anyone know if it works? Has anyone tried it? Please help to fix my autothrottle problem when ILS is on. I've used the merge from www.avsim.com just type in "merge" on FS2004 and it should be there. He's done a great job, just the ILS is hard, just hard to control.Please help, sorry for posting this again.Please reply, thanks. Don't know what's wrong with the autothrottle on ILS. :(
