Have a 2010 m8, that is having an issue with cutting out that I indicated on a previous thred. Still having same problem think it might be the throttle position switch, but I disconected the plug to the switch I think and still had problems. Then I descovered that the spark plug cables had been rubbing, but they had not gone all the way threw yet but I replaced anyway. Now I got confused about witch wire went to witch plug on same cylinder, don't know if it matters and if so how do you tell
