Does your car make air hissing noises when jacking it up? Or after you shut it odff? If yes, you have a leak.
My car, and my friend's as well, adjusts it's height after shutdown, and sometimes when opening the door or locking. My indy advised me that this, along with the hissing sound as the air self-bleeds, is normal.
So, not all hissing sounds indicate a leak! BTW, new front struts (under warranty by the last owner on the VMI) as well as new pump.
Does everyone elses lower a bit and adjust after shutdown or door opening?

Yes, it is normal, and it has been discussed a number of times in the myriad airmatic posts. After shutdown, the ride height sensors are still active for a time. When yiu exit the car, it rises just a but. The ride height sensors register the rise, and direct a short bleed of air to lower the car to the prescribed height.
