New to this group but I found a lot of useful information around.
my S320 1995 Vibrate at Idle [?], I change the sparked plagues just a few weeks I check the system using Diagnostic computer but NO fault has been shown [:)]. any recordation will be thank for it.
do this test - at idle, in gear (assuming auto) - turn steering to lock - does vib get worse? yes? then new mounts needed. common fault. is vib worse when cold and in D? yes? - mounts...
