I have a 54reg Renault Scenic 1.4(Megane) The engine starts first time everytime but as soon as I take my foot off the gas it cuts out, It doesn't 'tick over' This happens everyday hot or cold even if the engine is warm. After about 200 yards of driving it is ok and will tick over and not cut out. It's only for the first minute of driving. I have had it checked over and the garage can't find anything wrong with it apart from I need to keep my foot on the gas when i start it up! Service has also not sorted the problem? Please help it is stressing me out!!!!
