Vauxhall Astra - Misfire - crol

Hi I have a Vauxhall Astra 1.4 petrol, 2015. It has a intermittent misfire but there are no lights on the dash. It seems to have got worse when it is a hot day. Plugs and coil pack seem ok, could this be a faulty ECU?

Why do you think the plugs and coil pack are ok?

I thought I had this on my Yaris, at 80MPH in third. Found it was the rev limiter (I did have another three gears)!

I have swapped them over from another car, why I say seems, was because it slightly misfired on the other coil pack, but only once then was ok after that. When I swapped them back mine worked ok until the next day.
