Hi what year is the car?
What's the actual issues rather than the fault codes, has the cam belt been replaced recently has the engine earth strap been changed, what's tge battery condition?

the battery was replaced in march but the battery has gone flat a couple of times also belt looks fine its only 2 months old changed by myself nothing was damaged the car is ideals really bad like its missfiring but the spark timing is fine and spark plugs have been check

Often that upsets the relationship between top and bottom timing sensor,

That then wants plugging in to reset the system

Flat battery, un plug the Bluetooth module in the rear passenger quarter panel, assuming the car has it, also replace the earth strap if its not been done.
The re learn procedure is required after replacing the timing belt( it's so easy to muck up the replacing of the belt I'd only ever have a garage do it and even these get it wrong on this engine) however given your symptoms something is definitely wrong, even cars where it's one tooth out behave "normally " until high rpm?

Try unplugging the ECM and then refit the plug. Nothing to lose!

Any update?

Did the car have the timing inputs reset?

So your first entry was the 15 Nov and now it is 1 Dec so any updates so far?
For a new battery to go flat quickly normally means that there is a item leaking energy even though everything is off. Normally the suspects are added radios or the like.

And if the car has Blue&Me, a faulty bluetooth module is usually the culprit
