MitsuStyle - View Single Post - misfire on cylinder 4 with AEM, 1990 DSM coilpack setup

I swapped injectors four and two. No change, #4 is wet, and #3 is almost as wet. I am starting to think power transistor, which after unwrapping the wire tape to it and the coil plug, I realize is just a dang switch that changes between coil 1 and 2. So I am really leaning toward the transistor at this moment. I could make one last change, and that would be to switch the wire leads to each coil and see if 2&3 misfired. But I think I know how that would end, and it would point to the PT again.
