When moving my car on to the drive I was just moving it back another 2 do it when it almost stalled so I pressed the accelerator pedal just sitting still and when pressing the accelerator pedal it was almost stalling but when I took my foot off it would tick over fine a little lumpy but that's due to the cam.
After some serching around it seems to be common with the aggressive catcam and cold start fueling off to 1320 in a coupple of weeks so will get them to check it over when its there.
