I have a 1983 Cadillac 4dr sedan which has the service soon light on all the time. The codes I got from the computer were l.8.8  29,52,53.

Could you help me find out what is wrong with this car.

The codes you provide appear that they may be OBD1 codes (cars pre '96).  Here is a url     https://repairpal.com/gm-obd-I-code-chart

Is the car performing poorly, and how long has the service soon been illuminated.  I might clear the codes and see which one comes back.  You listed a 29 and that code isn't represented at the site I checked.
