[Kev_md]

Any help would be appreciated,had the car serviced a couple of months ago ,new plugs filters oil etc,then had a coil pack replaced ,but the car seems to have a slight(what i think is a small misfire) when idling,the rev counter moves maybe 50 /100 revs ,but not all the time ,is this normal(french) our could it be something else to P-ss me off.:S just to add its a 54 plate 1.4 dynamique 54 plate with 21.000 miles,cheers.
