Notwithstanding everything that @Datatek said - who should be listened to most carefully - I had the same issues exactly as you first described them - and again, not withstanding the fact that multiple things can be wrong at the same time and compound a problem, after a lot of mucking about with my EAS over a very long time - replacing a faulty sensor eventually cleared all of my issues. At least for a while....

Oh I fully intend to take a great amount of notice of @Datatek and anyone else, best way to learn anything.
Thanks for your input re the sensors, much appreciated
 
If you remover the eas delay relay under the passenger seat it will not self level and will show if a bag is leaking that corner will drop
if there is a leak then the pump may well need a rebuild as it will have been working more to overcome the leak.

+1. Rules out the bags at least.
 
Failure to go full height, certainly quickly, can be compressor wear. @kurtjohnson10 sorted me out a brilliant kit of parts for Otto. The new airhose was vital as the old one had split lengthwise, and even without that the output was weak.
That overhaul plus 4 new airbags has transformed the ride and handling. 3 new compressor mounts sorted the droning noise.
He very occasionally hunts for height or dances gently at traffic lights, but sorting some blocks and resetting the sensors should clear that.
