I had similar problem to others below - poor idling as well as cutting out at lights. A mumber of other forums suggest the poor quality of the Sagem SL96 ECU fitted the same as fitted on my 1998 1.4i. I had this checked out with an analyser and the report came back that the stepper motor was faulty. I had the stepper motor (which does control the tickover) replaced and this seemed to cure the stalling but the revs kept on varying from 750 to 1800 revs, not all the time but intermittently. When I took it back to the garage they replaced the stepper motor again but then it would not tickover at all. He replaced the old stepper motor and the same thing happened, it would not tickover at all. He then replaced the ECU which had no effect at all so he replaced the old one. On testing it with his analyser it said that there was an intermittent fault with the stepper motor!!! He replaced it with another one but this also had no effect. Now I have a car which will not tickover but otherwise drives fine.
Please has anyone any ideas what could be wrong?
