code help??

I got a check engine light, today pulled the codes and got 14 and 28 anyone have a FSM and can look at what this is for me.. BTW it is on a 93 california cruiser,

14: ignition signal. Igniter and ignition coil circuit, igniter & coil, ECM.
28: #2 02 sensor

thanks... that could be why when I checked the timing it was jumping 2-3 degrees at idle....in maintence mode.. so either the pickup or the coil and it took out the O2 in the process.... great.. wonder how the ECM plays into this...
