Answer 1

This is the ECM, Even if the engine sparkplug well had oil and oil soaked the ignition coil, the coil would not be the fault, The trouble shooting tree mention the CKP that because it is capable of making a spark knock but that in itself is very rare, The camshaft position sensor is mention also but again this is the real world it does not cause P1320. You need to trouble shoot this electrically measure the red wire for voltage, if there is none you need a ECM. By the way when the capacitor was replaced did you clean out the connection before installing the capacitor
