I've a question : are the two sparkplugs ignited at the same time or is there different timing hold by ECU (on the same cylinder ) ?
One of our guy cross the coils HT wires & tell us that engine don't run well when he do that??
Coils have their own wire from ECU, & are tagged in & out, I can't find anything throught tuneECU on simultaneous or timing ignition.

In the capo forum they confirmed with a scope that the two plugs spark simultenously.
Probably your friend has one plug which is not firing usually caused by a dead coil.
The center plug is more important than the side one.
Often a faulty coil doesn´t trigger the fault code.
Search for how I check that the coils are functioning. It´s 100% accurate and quick.
