Mein Auto: BMW 740I
94 740i 80k.. Rough idle.. white smoke.. mil light.. stomp 1222, 1213

hey people.. I was wondering if somebody could point me in the right direction.. I perchased a 740i around 8 months ago.. car ran perfect (seems like) up until the temperature dropped over here.. I ve been reading the boards and im a little confused at where to start.. should I start by replacing o2 sensors??.. or is it more likely the OSV valve?? vacuum test?? any help would be appreciated
