Yesterday while motorway driving we noticed that our focus would on the odd occation misfire and loose power for about 10 - 20 seconds. This would happen in a varity of gear ratio's. Im going to change the plugs and HT leads, but have heard about the coil pack might be at fault ? Also noticed that the speedo needle would flick when this happened and then settle down again. anyone got some advise, am I on the right track. Forgot to mention, no warning lights are displayed when this happens
