i was driving home today and a horrible smell came into the car like a eggy burning smell.

the car started running a bit lumpy, i noticed its lost some of its power, i know bit about cars but not much. I realised 1 of the spark plugs wasnt running in checking this ive noticed that there is no spark going to plug number 4 from lead.

Early on in the day I replaced the screws in the back seat, as a couple where missing, the screws i replaced where probably 2 and half inches long, is it possible ive done any damage or puncutred anything whilst replacing the screws.

the car has a 1300 fuel injected engine with a electronic ignition.

Thanks

screws in the back seat wouldnt have caused the missfire, its most likely a coil pack or the lead to the plug.

Yeah it definately sounds like you need a new coil pack and possibly new HT leads.

Had exactly the same problem with my Fiesta 1.25 Zetec not too long ago.

The smell is coming from the cat due to misfiring.

I was told it's a common problem.

unbolt the old unit, swap the lead and refit the new.

i think that there's just one coil pack on your fiesta, it's not a difficult diy job, just 4 small bolts with torx heads on, the bottom two are a bit fiddly to get to, but if pull the top section of your air cleaner off it makes the job a bit easier.

Do you remove the air box or do u have to take all the fuel injecters stuff off the top of the engine, or do you access it from underneath, as cant seem to get to the coil pack to undo.

Any help is much appreciated.

Thanks
