I guess my title is a bit miss leading, I was going to type " late 90's " but decided to put the actual year and didn't remove " late ".

Next time I'm under the car I'll measure and tie off the front and rear height sensors. I have noticed ( since I got the car a year ago ) that when turning the lights on, they start off low and rise to proper height but that is probably he safe default.

I do know that ,under braking as the nose dips, the headlights will rise but, that is after a slight delay and at a slower rate. The jiggle I am getting is a rapid jitter like the headlights are loose ( they are not ).

But, I should measure sensor resistance over the travel as the sensors may have open spots.
