S4s misfire at around 5k under hard acceleration

[fflyingdog]

Pretty much what the title says ,under hard acceleration around 5k rpm i have a misfire ,checked all the usual suspects pipes freescan etc nothing abnormal ,i am thinking that maybe i have a coil pack about to give up the ghost ,car has done 70k miles.Any body had similar issues? Plugs and leads are new as i had exact same problem earlier or could i have an engine with a hunger for plugs ?

many thanks

Fixed bad coil.

Apparently its a common GM part or something, did Geoff fix it? He did mine, cost me a kidney and most of my sanity...

Yeah i took it up this morning ,when i got there the car was only firing on 3,i changed the coils whilst Geoff berated me for dropping a bolt ,also changed a couple translater joints, gear change alot better now.
