Hi All,

I am newbie, a want to be DIY home mechanic, new to petrols and ford, my wife's car is 2014 Ford Fiesta 1.2 petrol. I believe this was the Yamaha designed engine?

Had a misfire on cylinder 3 a while ago, changed the spark plugs and HT leads, fault went for a month then EML came on.

Fault Code above same fault misfire on cylinder 3. 

I have ordered a new ignition coil pack as next cheapest solution.

If this doesn't work, is there anything else I can try or if this is a common issue on these cars?

Engine done 54,000 miles.

Thanks,

    Should be just the coil pack unless spark plug is us.

    Thank you for responding, I changed the coil pack the weekend, fault light was still there as couldn't delete fault code, then it disappeared, hopefully this is resolved.

    Gracias por responder, cambié el paquete de bobinas el fin de semana, la luz de falla todavía estaba allí porque no se pudo borrar el código de falla, luego desapareció, con suerte esto se resuelve. 

    Hello, is your problem solved?
    I'm in the same situation as you, follow the error number P0303 and I don't know what it could be.
