If the codes have never been cleared after a repair has been made then every code since 1991 will be present.
If the car is in running condition it would be best if you cleared all the codes and started over to see which codes are still viable.
You should disconnect the negative battery cable for 5-10 minutes. This should allow the computer to reset. Then drive the car for about 10 miles which will allow the computer to reteach the system. If any codes pop up after this then they are active problems.
If this helps, please send $$$.
