hi all iv just bought my first focus its a mk1 2003 but i only bought it as a spare of the moment thing because the owner said it had a miss fire,so I changed the plugs leads and coil and still the same but Iv been reading and everything points to a sticky valve so what do you guys thinks and is it easy to do if it is

    How severe is the misfire, does it do it at idle, when revving or when accelerating ?

    Have you tried re-gaping the spark plugs to 1.0mm ?

    It does it most when on idle but as Iv only just got the car I'm not sure if it's down on power but it feels like it
