I am a newbie to this site as i have only just bought my first astra! i have had the car a couple of weeks now and every now and then i notice a slight missing at around 1500-2000 revs its only very quick. hard to explain but its as if you were backing off and on the power at the point when the turbo kick's in/out. apart from that the car runs great. sorry if this sounds a bit daft just wondered if anybody had any ideas or is it nothing to worry about?
Thanks for looking!
