Ok folks, Driving to work yesterday morning and the EML came on when i got to work i tried resetting it using the dash trick and it was still there.

When i finished work and started the car, there was no light
I plugged my fault code reader in when i got home from work this evening and its given me this code

P2300

i have searched the internet and I gathered that it has something to do with the wiring between the ECU and Coil pack.
I had a look and everything seems ok, so im not sure what to do.

anybody else had this problem or can someone point me in the right direction to fix this?

any help is appreciated

TIA Tom

needs a n ew coil pack then if the wiring is okay avoid driving as the misfire can damage the cat for a genuine coil pack you have these http://www.ebay.co.uk/itm/FORD-FOCUS-MK2-1-6-2004-IGNITION-COIL-PACK-1119835-/250905557797?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item3a6b22fb25

used them for my mk1 and had no issues or theres the bosch ones which are oem http://www.ebay.co.uk/itm/FORD-FOCUS-MK2-1-4-1-6-16V-IGNITION-COIL-PACK-2004-GENUINE-BOSCH-/230768124980?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item35bada2434

Thanks, Im gonna give the plugs a clean, I think i know why its messing up, I let it run low on petrol. so i guess that it has brought a load of crap up from the tank causing it to chuck up a code.. had no misfiring though.

7 out of 10 cars that ive done with that code had either faulty ht leads or a coil pack that code refers to the signal between the coil pack and ecu so fuel wont do anything and the misfire may be slight and at higher speeds but its always plugs leads or coil good luck

For the life of me, I could not get the plugs out. I have the attachment but it wouldn't 'click' on, if you know what I mean. such a PITA.

I have not bought any thing as I might put it in for a service, im not sure the dealers did it before i picked it up. even though there is a stamp in the book.
