Hi hope someone can help. 100 miles Post a service (oil, oil filter, gearbox oil, fuel filter) the car is going into a limp mode then stalling with the stop warning. Error code is f40a. No engine warning light. Oil check on dash is "ok". Oil level is good. from cold will run fine for 5 mins. Once warm and revved will sometimes get amber triangle and limp. Sometimes stall with stop warning and sometimes both. Does this when stationary. any ideas would be gratefully received
