Hi Gareth,
the plugs were put in a day ago when I did the full service so we had no problems with the map, the air filter is a mushroom filter and I have cleaned it out thoroughly, but my coils are old and haven’t been renewed. So I’m assuming if anything they’ll be the problem. Just found it a bit strange how he only mentioned it after the map was programmed and after it started misfiring not before like you would expect.
thanks Alex
