Random misfire/hesitation at WOT
Something that my 2011 mustang gt has been doing periodically that has been baffling me is that every once in a while when launching at the track, I'll get a hesitation or a pause while at WOT. It's almost as if the car is misfiring or pulling spark. I haven't been able to get it to do it when I'm datalogging either. It's extremely random. I can do 20 passes down the track with nothing and then all of a sudden one pass I'll get that hesitation feeling after launching. Does anybody have any ideas or has experienced this as well? The random nature of it is driving me crazy. I think I would more rather it did frequently so I could pin it down easier.

This isn't my car and my car is an Auto, but this is exactly what my car is doing. Watch how the car hesitates at about 41 seconds in. There must be a nanny either reducing torque or retarding spark. I just need to figure out what nanny is doing it. I need to get this datalogged and catch it red handed.
