It's a possibility, but there's no guarantee. It could be a countless number of different things.

My wifes old Saxo 1.1 had stepper motor issues, would sometimes rev at 2000rpm when it should be idling, sometimes it would cut out when you declutched stopping. Basically the stepper motor was screwed. Easy replacement if I recall just 3 bolts and about 15 minutes.
