The rear end drops on the tires and if you start the car it will rise but then by the end of the day it drops (like a low rider cars)

My suspension is sitting low in the back and my car is really bouncy.

I have the same problem. The rear goes down from time to time. When riding down the road I can feel the back getting low. When it does, the ride is very bouncy and very uncomfortable. When I stop and turn off the engine for a few minutes the back rises up again and the ride is smooth sailing. The air compressor for the rear may go out for a few days or I may not have that problem again for a few days or even weeks. Its very frustrating!!!!
