Hi.
My Cooper S R57 2009 is misfiring when cold or wet, I've changed the spark plugs and Coils I also ran some engine cleaner through it to clean injectors Etc. It seems a little better but still misfiring and hesitant.
The unusual thing I've noticed is if I drive the car in Sports mode I have NO problem with misfiring or hesitating, it's a mystery???
Does anyone have any ideas of what I can do or what causes this problem?
Many thanks everyone.
