I have the same car and HAD the SAME symptoms i replaced the coil pack.
problem gone
hope this works for you too they can be expensive so my advice is to ebay it and get a cheap WORKING one to isolate this fault

Dat is on my todo list!! Gonna check my plugs first then my coils, give the egr valve a spray with carb cleaner! Anyone know weather ill need to replace egr gasket? As i wouldnt be changing it just yet? Ive cleaned out my carb with carb cleaner also my air box etc. so der all fine got rid of all the grease and blocks its actually made throttle more responsive massive improvment on acceleration!! Had car serviced 4 months ago plugs oils all filters including fuel and my mind has a funny feeling it cud be coils as a few mechanics have said so so fingers crossed!! :)
