The problem your describing is a very common one for the Mark VIII. The problem is excessive moisture inside the system.
Dryers only absorb moisture for 4-5 years. After this, the moisture just "collects" there. Then on the vent cycle, the air goes out in reverse of how it came in. The problem now is that all that air pressure pushes all that moisture accumulated in the dryer through the compressor. Basically giving the compressor a bath everytime the car vents! These compressor are designed to run bone dry and won't last long if they have to put up with much moisture.
At this point, you should figure out if you want to stay with the air suspension or convert to coil springs.
