check engine codes

[Rotary#10]

its my 91 n/a FC
the following codes poped up during my return of San jose.
1, 2, 17, 30.
Code 1 is the trailing ign.
code 2 is the CAS
17 is the feedback system?? whats that do?
code 30 is the split solenoid valve?

okay what would be a good place to start checking for problems first?

17 could possibly be O2 sensor.

And it's the split-air pipe solenoid.
