I have a 1997 Lincoln Mark VIII 67000 miles real good shape. The problem is that the air suspension system in the front does not stay inflated, the front end goes down when the car is off or at speeds exceeding 50 mph (like on the freeway. I had the car to aLincoln dealer, they told me the system was fine (obviously they did not test.) I have been told could be a height sensor? Looking for input. approx. estimate and a good mechanic.

For local mechanics, here's a link:
You will have to call some of those and be discriminating, because Lincoln air suspensions - although not terribly difficult to diagnose - are intimidating to many.
The newer vehicles (OBDII - like yours) are easier to diagnose than the older ones.
When you say the front "goes down", do you mean all the way down? If so, and it's nearly impossible to drive without bouncing all over and grounding out, there must be a leak either at the drier assembly, a line, or the air spring itself.
Height sensors are typically constant issues, not intermittent. There is a plastic link that can come off (but would always be off...thus always show a problem), and the sensor itself is either good or bad, not ever really intermittent in a way that it causes fluctuation of ride height.
Good luck with your situation, and keep us up to date on your progress.
