I have a 1998 Ford Fiesta Zetec LX 16V 1242 engine.The engine stalls when the clutch is depressed for more than a couple of seconds at road junctions.The problem is worse when the engine is cold but does still stall occasionally when the engine is warm.Engine starts easily and runs normally otherwise,but often does not tick over smoothly when left in neutral.Have had spark plugs renewed but has made no difference. If anyone has any ideas what it might be plz feel free to leave me a reply.Cheers
