missfire

[ray selley]

evening
I have a missfire more noticeable in low gears from cold . but I can still feel it at 60mph
1.2 16v 2011 99000miles
I've checked the plugs all ok.
I was going to buy a coil pack as it is one pack for all cylinders? but there is not fault codes. I would of thought there would be.
so iam going to do a compression test but I can't find the fuel relay to isolate the fuel. the bottom end is noisy for a minute or to when started from cold.
what are your thoughts and experiences?
thank you Ray

up date.
I have now done a compression test.
left to right as your looking at the engine from the front.
no1 175psi
no2 180psi
no3 180psi
no4 180psi
cold engine. dry
so no issues there.
it ticks over fine.
when I remove the plug leads individually running i can hear it sparking.
engine temp sensor reads 80⁰ on my scanner when the gauge on car reads 90⁰. is that ok
if any one can put me in the right direction.
thanks Ray.
