Can anyone help?  Im still having this issue. 

My procedure is as follows:

Enter ILS frequency and course in the pedestal radio. (BTW ive noticed that the Front CRS heading on the FMC Approach page often is different to the current charts.  For example it was 46 degrees for Runway 04 at KLGA but the charts show 44)

When turning on to final press LOC
Once localizer is captured press APP.
All 3 CMD autopilots arm themselves but then the FD does not track the GS.  It always, 100% of the time, takes me too high and mostly off course (I assume this is because the Front CRS is wrong).

Any ideas?
