On mine it was the coil packs. Had those along with the cables replaced. Been fine since.

Does it happen when cold or all the time?

Phill,

If you book a T4 session it will identify a faulty ignition coil and tell you which one. That will save an awful lot of guesswork, heartache and money spent on speculative purchases.
