It happened to me quite a few times but it's really tideous.. I never caught up a pattern but I couldn't not notice that whenever I floor it, it accelerates sharply to 3krpm, hangs there for half a second and then continues its journey up.. Any ideas? Car was always serviced every 6months and is due for her next service this week for oil + inspection. I hope it's not related to the MAF or something expensive of the sort.
