Had the same kind of problem on mine and turned out to be the pcv so bought a revamp kit from dubtek and its alot better and smoother to drive  :happy2:

Mine has the same issue, have changed PCV, coils and plugs and still no change. Just haven't been able to get it to a decent garage for a scan.

Let us know what yours comes up with :happy2:

      It went in to main dealers today, it turned out to be the pcv, although i have not picked it up and driven it yet so fingers crossed thats the end of it.
