Hmmm...I need to do this as well. I’ve noticed the same on mine.

Should the bladders always hold some air/pressure in them or is it normal to deflate after sitting for a while?

if everything is in good shape they should hold air for quite a while, mine has sat for days and still were nice firm, that's how I found out I had a leak they would be deflated in the morning or after sitting for several hours, plus I could feel it wasn't right while driving

You guys got me worried about burning up my air pump, so I ordered the Arnott AS2708's from RockAuto. Should be here by Friday

Remember to double check the ABS cable connection above the frame near the top bolt. You barely bump that thing and you'll get a Stabilitrack and Traction Control error.
