Another question from a newbie.....my air bags (inside the coil springs) on the front suspension, loose several pounds of air over the course of sitting for a few days, maybe 10 pounds in 3 days. Is this considered normal??
As Jeff said, the bags should retain pressure for several months. OTOH if the bags were damaged, I wouldn't expect them to hold air at all. You might try replacing the valvle cores. They're just like the ones on the tires of your car.
