   As above seems to be random. I start the car some days and it runs mint. So quick and smooth. Other days it starts rough and feels rough/lack of power.
   
   I was thinking spark plugs?

   could be in need of a service mate. Plugs, oil filter, fuel filter, etc., you know the usual. Maybe the coil pack too.

   very good service history on it and was fully serviced just over a year ago before i bought it. Oil changed twice since i have had it with silkoline pro s 5w-40.
   
   Might give the sparks and coilpack a shot though.

   Always do the sparks, ht leads and filters first. Mine done this so I got a new coilpack and it turned out to be a crap sparkplug.
   
   Check the sparkplugs and see what condition they're in mate
