Hi colin, cant remember what model, but it was misfiring in 2012 when i stripped it down changed the plugs and one coil pack, changed the leads, drove it for a couple of months then had to take it off the road for health reasons, it was laid up for twelve months, got it back on the road at the start of the year, its been running great till wednesday then started to play up. its done about 2500 miles since i changed them
