car threw a P0300 code and ran rough with check engine light flashing , after reading the code checking connectors i had a look at the coils and found that the 3rd coil for cylinder 1 and 4 is not producing sparks at all , i replaced the coil and still have the same issue , thinking it might be the ICM ( ignition control module) but i am not sure , 4 cylinders still get signals and sparks i don't think its a sensor but i don't have enough knowledge about that what i also don't know is if there is a fuse for the coils so if one goes the others still work? i really don't wanna start replacing everything just to find out it still there
