Car is fine idling when cold but there is a de table slight misfire at idle when the engine is warm. The CEL also goes on and off but will come on mainly after the car has warmed up.
I’m aware this error has shown on other member cars and would like further info as to what the issue may be or was your experiences.
Many thanks in advance.

So that code is saying the camshaft is out of time in relation to crankshaft position.
That could happen when things like timing chain tensioners wear out.
Causes excessive play in the timing chain
you could find a scanner that reads camshaft deviation as a check.
If you have excessive cam deviation that would verify the codes.
or verify proper timing by aligning the factory timing marks.
If the above is all ok then I would look to the camshaft position sensor being faulty.
