SOURCE: engine runs like it has a miss fire fault code is

The fault code appears to be telling you the 02 Sensor nearest the exhaust manifold. You have two on yours. You very safest bet is to verify with your local dealer. The New Car Dealer will give you the code meaning over the phone if you give them your VIN number and the CODE.
Be sure to check on recalls as well. This can save you thousands of dollars on some cars.

Remember if you install the new 02 Sensor to be sure to use a thread compound to save trouble for whom ever has to replace it again.
ALSO - have a stone cold engine to do this. You will want to invest in a pair of gloves for removing the old unit as busted knuckles is legend when doing these types of repairs.

Once the new part is installed; remove the negative battery cable for 3-5 minutes then replace and let the car run for 20 minutes driving time and it will 'reset' your on board computer.

SOURCE: my fiesta is mis firing

That doesn't have anything to do with the car misfiring. All the heater circuit does is warm up the O2 sensor a little faster so that it can start working a little faster. If the O2 where not working or if it where stuck lean or rich there would be a code specifically for those. If those codes where present I would say your on to something by suspecting the O2 sensor.

To find a misfire you can pull off plug wires individually and see if the RPM changes, Check the spark plug condition, Check for good spark at each plug, wet down the ignition wires with the engine running and see if they leak spark, etc.

My fiesta is mis firing and i bought a obd scanner and the code has come up with p0030 ho2s bank 1 sensor 1 heater circuit how do i fix that to keep it running??help please....

P0030....HO2S Heater Control Circuit (Bank 1 Sensor 1) and to be truthfull i havent a clue as to what its refering too , i can only sumise its something to do with the heat going into the inlet manifold from the cooling system and a sensor is reading the temperature and adjusting the fuel mixture accordingly .sorry i havent been much help for this but if you ever change a front wheel bearing then make sure the grey coloured paint is fitted to the sensor side (interior by drive shaft) or the ABS light doesnt go out

Engine runs like it has a miss fire fault code is p0030 can any one help on ford fiesta 1,4 04 plate

replacing "heated oxygen sensor", (bank 1, sensor 1), on your vehicle is the most likely fix for that.
Seeing how you should only have one bank, then it will be the heated oxygen sensor ahead of the catalytic converter.
