my mini coooper s r56 2009 45k miles started missfiring on two cylinders. the garage later told me that the car is only running on two cylinders. the mechanic i use who has plenty of experience on r56's cannot find the problem whatsoever, the car has previously been remapped by the last owner. the engine oil was smelt really strong of petrol if this helps.
i have changed the coilpacks/sparkplugs but no luck. any help would be deeply appreciated
