My 2013 car is now stuttering. It is doing so quite a lot and quite violently on occasions so I am looking for any suggestions as to what may be wrong and more importantly if there is anything I can do to help. I have changed the spark plugs and it ran better for a while but it is back. I have adjusted the HT leads and it improved but it is back. Any suggestions? Just to add to the inconvenience I am in rural Italy on a tour.
Thanks,
Richard
