Well I have changed the plugs and so far all seems well. No misfire and no engine light. The manual says the plugs are good for 40,000 but probably didn't take into account the time to get to that mileage. Anyway thanks to everyone on here who replied and helped me save a fortune. Keep up the good work. John

Thanks for the quick response Ken, actually now you mention it the mechanic did mention that it did show cylinder 3 as well on one of the readings. A new coil pack is £80 which may be the cost of the dealer investigation then I would have to pay dealer prices for the part. The misfire is under heavy load which makes me think it is a coil breaking down. There are no HT leads as the coil pack sits straight onto the plugs. I think I'll get a new set of plugs first even though they look good and see how it goes. John

I have a 2002 Fabia 1.4MPI which intermittently misfires. The engine light came on so I took it to the dealer who says Cylinder 2 is showing up and could be plugs, injector or coil. I measured across the injectors for resistance and they are all the same. The coil s are a single pack with just 4 wires in the connector so my question is: Can I measure the resistance of each coil as I have tried to measure each to earth with no luck. Before I take it back for a more thorough look by the dealer I would like to narrow it down. Any help would be appreciated. The car has done 26K and we have had it from new. This is the first problem we have had. Thanks in advance John
