Ecu Code 73 on 88 Hatch

I noticed that my check engine light came on today on the way home and the sub was idling roughly. Once home, I checked the led on the ECU and it was flashing a Code 73 which equates to an Ignition Pulse error.

 

I did some quick searching around the forum for others who have experienced a code 73 and didn't find anything.

 

Does anyone have any thoughts on this code?

 

Thanks.
