Misfire cylinder 1

[Antti O]

Hi
My car flashed 3 times CEL , then i got error memory diagnosted. There was sporadic error misfire cylinder 1.
Coil gone? Is that best option to buy full set of new coils, you can find easily under 30£ the full set from ebay, but what is the quality?

DF436 misfire detection
DF059 misfire cylinder 1
DF109 Fuel minimum level caused misfire

I would check the connections first and that the coil end is making good contact with the spark plug
