On my AAN with low mileage, I had a hesitation/misfire between 3 and 4k roughly, and then it pulls cleanly, with oem original coils.
So speed in my 1.8T style coils from another an ABY engine, and the hesitation /mifire is gone. Car pulls like a machine with no hesitation to the red line.
Just posted for other's benefit.
TBH, I love that it is fixed, and the way it pulls, but love the look of the oem coils. :roll eyes:
Also changed my bypass valve a few days ago which improved things a bit, pulled with a bit more vigor, but didn't fix the misfire.
So I obviously had two faults.
Gonna swop in a new S2 N75 valve in a few days to see if there is any change, not expecting anything to get better, but a new one can't do any harm, will post result in due course.
HTH.
