I have owned my '92 Civic DX for almost 2 yrs and for most of that
time it has had an off-and-on severe vibration with apparently low idle
speed, while still giving good performance and gas mileage. Well, I
read at some time in this group about engine mounts, so a few weeks ago
I went out, opened up the hood and tried to see what they looked like
(discovered they were circular black things, mostly). I saw this nut
connecting the top left mount to the engine which was just sitting there
half-way up its bolt, not doing anything, and when I applied a socket
wrench to its partner nut, that was loose too. Tightening both these
nuts to about their correct torque has got rid of the severe vibration!
