fiesta mk6 missfire

[craig1989]

hi

have had my fiesta for a year now and has been problem after problem

my car is missfiring on cylinder 1 and 4, i had the coil pack changed 5 times and has made no diference same for the leads and the spark plugs.

when engine is running taking the spark leads off the coil pack there are no sparking/elictrics going through to 1 and 4 from the coil

i have had ford to look at it they said that it sounds like a pcm update and then when i booked it in to get the update they said that they dont want to update it as the last time they done so it made another car worse any ideas on what it might be.

when car is cold its at its worse stalls when clutch is depressed idles form 500 revs to 1000 but when car temperature is warm the car is fine only slight notice but runs although there was nothing wrong...... engine managment light on and reader said cylinder 1 and 4 missfire and intermittant coil pack and it also said something about a circuit problem have had the circuits checked though something to do with the circuits inside the coil pack lol any one know about this list of problems please help
