had same prob as claire above. replaced plugs, leads and coil pack.
all was well ... for a couple of months and its just started playing up again :/
could be due to the fact that i bought cheap aftermarket parts rather than genuine ford ones?
ford want £100 just for a set of leads whereas the non-genuine ones were only £25.
think im gona try find a set of genuine ones on ebay before i splash out £100 just incase its not actually the leads causing the problem.
extra info: yesterday she was driving fine until i got on the motorway then started to misfire and engine light came on.
so i pulled over for about ten mins, check lead connections n when i drove on she was fine!
drove to destination using A roads instead of motorway, no probs.
after an hour or so at destination (so engine had cooled down) i go to drive home and she is misfiring even in neutral when i rev.
so kinda back to square 1 with this one???
input from anyone greatly appreciated :)
