Car Running Like Sh1t

[Suspense]

recently on cold starts my car has begun to devleop what feels like a misfire until it warms up...

The car is jurky and it seems as though 1 cylinder isnt working..... however once i get up the temperature abit.... it goes away and the car runs fine...

i know coil packs are one there way out... however that shouldn't cause it should it?

I also have forged piston? could it be piston slap???

if so how come it hasnt hapenned before

:S

Mine was exactly the same, it was the coil packs in my case.

They were cracked (and to my thinking), when cold, they were damp and this helped the cracks to short out.
