Zero out that fuel trim on cyl 2 to see if that has anything to do with it.

So i worked it out the problem i put the genuine hitachi coil stalks on and runs perfectly so the aftermarket short stalks where the problem

Ah, good work, that was going to be my next question.  I too have seen spark leakage with poor fitting stalks on these coils.
