VIDEO - Ok, found out it airs out weird sometimes too. I haven't had air very long, but I adjust my ride height as I go, usually running around 45-55PSI. If I go to air out a little on the road, it will just do this, usually on the first try. I was just messing with it a lot because I knew it would eventually do it. Side note: its my driver's front.
Also note that I'm the one airing it up/down quickly. When it makes the 'duck' noise and the yellow (left) needle drops far, that's what issue I'm having.
Alright, so I have 8 SMC valves, and this switch box. When I air up, I usually do the back first, and then the front, using the back up, then the front up switches (individually.)
Today, I watched my gauges, and when I aired up the back, the passenger side rear went WAY higher than the drivers side, and just kept inflating. I quickly aired it out and it stopped. The front did the same thing, but ONLY on the passenger side. It's happened a few times now, it's not every time, and it just started today.
Now, if I air each bag up individually, it doesn't do it, but that could be the fact that it happens intermittently.
Any ideas? I have yet to check grounds/power yet, but I really can't think of what it would be.
