Have you checked the wiring to the injectors?

No wot should I b looking for

I would start by taking one plug of each injector at a time and see if the engine note changes. If you get to the cylinder with the missfire, remove the plug and nothing happens then you could have a problem with the wiring or the injector. You have had new injectors and you mentioned it went from one cylinder to another so it could be the wiring and you had a new coil pack but did you replace the leads for new genuine items?

Don't be silly, the first thing you do when you have an issue is to post it online

Got new wiring for the injectors coming after that it's just the wiring to the coils and don't have a clue wot to do replaced everything can think of like I said once over 1000 rpm it sounds brilliant but once it drops it's sluggish and engine light on
