Engine giving me codes

[Billy88LX]

I noticed some problems when driving in cruise control on the highway with some shuddering and loss of power so i pulled some codes and this is what I have

code 25 ( i couldn't find it in my code book)
code 73
code 74

These are all with the engine running. Its a 2.3L 1990 mustang but I put this in the 5.0 section because it would get more looks. What sould i be looking for with these codes? Thanks
