Default missfire under load

I changed my spark plugs today and had to diconect the battery. When the new ones where in it was missing under load at 3000rpm so I put the old ones back in thinking maybe a dead plug....but it still missfires ... im thinking coilpack but why would I just go down like that any Ideas anyone????

coilpacks can crack relatively easily depending on how old there are you could have done it whilst removing one.

You can tape them up if you need to.
Worth checking them first
I believe David at Welcome to the API website does a good deal but that may have changed with the current economic climate.

does it only do it under load as mine is doing the same but clears itself if you keep it floored for long enough then runs fine. Just wondering if mine has the same fault.

idles fine but as soon as you grt to 3000rpm it imposible to drive through im hoping it is a coil problem.. diconecting the battery wouldnt cause any problems with the apexi fc would it???
