Ok so it's got worse now,

My car idles a bit lumpy but at least regular but on acceleration it's juddering almost misfiring and now goes straight into limp coil flash as soon as I accelerate harder than gentle and is really juddery?!

Further to this it is getting harder to start now and when I started this morning the light flashed as soon as ignition had started engine ( I waited
For coil off before starting)

Is this all pointing to injectors still based on this info?

Hmm really need to get codes now
