Ford focus persistent engine light

[Stevo593]

Hi all - I have a 2015 focus ecoboost 1litre. Had persistent problems with code 0036 (lambda sensors) and proceeded to full catalytic converter, lambda sensor, spark plugs and air filter change. Now my EMG keeps illuminating with p0302 cylinder misfire, car spent 4 hours in garage and replaced the mass air sensor, no other issues found but after 2 journeys the light is on again. This seems to be an unanswerable issue and I am at a loss as to whether to stick with it having paid over £1000 for repairs or cut my losses and move on. Car drives well and there is no obvious signs of misfiring. Any help on here really appreciated! Steve

Will probs need a full diagnostic of live data to see whats a miss.

Is it showing the same DTC on dash as previous?
