Misfire at higher Rpms

[JoeyxGx2]

Sooo i was doing 70 cruisn then decided I wanted to floor it, so I did, but car at to of second gear right before shifting into third misfired about 3 times before shifting, it wasn't rev limiter.. Sounded more like detonation... Plugs, wires and opti are all new as of last summer, maybe clean MAF and new fuel filter, any other suggestions would help thanks
