1994 Mark VIII. Car sits for 3 days, the rear end is totally deflated. When I start it up, everything is fine, as long as I use it every day. I would like to keep air ride but will not rule out coil conversion. Any suggestions will be greatly appreciated. Thanks. :give

First off....:W to the LvC!

Second, the bags are prolly bad, and need to be replaced. The reason they deflate over a period of a couple of days and not all the time, is due to the fact that they prolly have a very small leak and the compressor can keep up with it on a daily basis, but allows it to leak down over the couple of days you do not use it. :Beer

just go coil over, it cheaper than bag replacement
