Could be a plug or an ignition coil fault ,which is quite common.But easiest way to check or confirm is to get a diagnostic scan carried out .

Common fault on these and the meganne is the wiring comming from the ecu to the injectors.To check you will need to remove the battery and box to get into the ecu plugs then from the ecu you will need to remove the tape from around the wiring and follow the loom that comes in front of the engine if you pull the wires apart and study them you will usually see signs of them been burnt.Everyone ive fixed with this problem the burn wire is usuall withing the first couple of feet so quite quick to find.If you do find a burnt wire check close by as sometimes there will be 2 burnt but never seen more than this.You will need to come back along the wires until you find a decent bit to join new wires to as if they show black then they will carry to much resistance and the problem will continue.
