This is what i have done so far.
Changed Plugs & leads.
Swapped coil packs between Cylinder 1 & 5 but no change.
Checked that there is a good earth inc from the coil packs.
Any help and info would be great as dont know what else to do.
Many thanks

Does the car mis-fire all the time? I know you say ok above 2000.....
