I think so but I haven't been able to verify it yet.
I think the spark plug wire harness creates cross fires and/or misfires especially with modern high voltage an high energy ignition. I spotted a damaged and "burnt" spot on the wire that connects the coil to the igniter.
I bought a new harness but I haven't had time to fit it yet and I have to bring the car back to my bodybuilder on Monday to redo the paint he missed the first time.
I will only be able to check when I have the car again in a month.........or more.
