Default air suspension leak question- '92

Hi all,

My 1992 LS has recently started to drop in the rear. AFAIK, original everything and never had a problem before. I know of the shocks going bad-- have read everything on it, etc.

My RR started one day, then 2 days later the LR goes down w/ it w/in 15 min. They are both intermittent since they started a week ago, but more often than not, they will drop.

My question is-- has any one ever found a leak in their air lines? It seems odd to me that they both started w/in 2 days of each other. I'm obviously hoping it's a line fitting I can fix and was planning whether to troubleshoot or just go straight to coil-overs.
thanks!

spray some soap to find the leak , otherwise add a small amount of some green slime to the lines.
