matrixops Posted October 31, 2007 Share Posted October 31, 2007 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.
