This seems to be a popular problem with these cars..
Just baught my 1993 cadillac sts in December and is now saying 'service ride control' sometimes, mainly if i go over a big bump. It also makes some mild clunking and bumping sounds when I drive over popholes etc. I assumed this was normal until reading a post recently. Anyways I got these codes and could use some further explaining of what they mean:

P013 - Right Oxygen Sensor Not Ready
A048 history - Low Refrigerant Pressure (dont care about this one here)
S011 history - Left Front Damper Solenoid Valve Short to Ground/Open
S055 history - Resistor Module Short to Ground/Open
S062 history - Left Rear Position Sensor Fault

I should also add my front tires need to be changed, they both seem to have slow leaks so I'm constantly filling them up - could this have anything to do with the problem? Or do I probably need new struts/shocks??

You need need new performace based shocks and struts, not cheapies. You may be able to trick car using override in tsb 00-03-11-001A to turn off light. Northstar system not designed to be disabled. Cadillac recommends to keep electronic suspension system on Northstar powered cars, but it will be $$$ to repair.
