coilpack?

I had this on one of my cavs a few years ago and it turned out to be the wire on the knock sensor which had rubbed through against the altenator. It would start miss firing like mad and then when it cooled down it was fine again.once I changed the wire it never did it again

Possible mate, but dose sound just like when the coil pack was deteriorating on my old track car.
