The car has been in the garage and they have replaced throttle body , spark plugs and the injector E.C.U. After the ecu was replaced car was ok for couple of months and now the problem have again surfaced and is getting worse. Initially problem was occuring one a month or so but now it is occuring regularly whenever and I make start stop journeys. The distance of the journey I thionk is not important but whenever the car is stopped and restarted within half an or so the problem occurs . If the car is left standing for few hours and then started it will take longer for the problem to reoccur.
I shall be greately obliged if anyone can suggest a solution.
Many thanks in advance.

Hi. Just wondered if you had any luck solving this problem. I have the same fault on my laguna 2 1.8. I have had the throttle body and the tdc flywheel sensor with the loom replaced but the fault still comes up whenever the car feels like it revving on it's own at 2000-4000rpm with injection fault displayed on the centre screen. At a bit of a loss and can't afford to keep replacing parts willy nilly. Any help would be great. Thanks.
