Many thanks, Guys! The trick with the "keg" under the dash worked 100%. I just can't believe that Ford would release such a design...
I put a brand new tensioner and the vibrations are a lot less worse ;-) I would say there is a 60% improvement, but still I can feel the RPMs going down in D. Perhaps they are going too low but I have no way of telling (my instrument panel has no tachometer). Any ideas how I can verify the RPM@idle? Is there a test point?
I am also looking at the DR side engine mount, as suggested above.
