After taking the Coupe out of storage (posh term for the garage) I put a full bottle of petrol improver in and topped it with 99RON. It did do the engine light the first trip but I reset this and then gave it a good back road open throttle session to heat it through (30+miles) and it has been fine since.
What code reader are you using please? I have 3, including a couple of fancy ones, and none want to talk to the Morgan Aero Coupe
