I have just bought myself my first BMW. Only had it a couple of days.
I managed to get it pretty cheap because of a few probs.
I noticed whilst cleaning it last night that there is a plug disconnected from just behind the air filter.
I thing its the Air/Fuel sensor. I reconnected it but now the car runs quite bad.
Idle is very lumpy, especially from a cold start. I had to disconnect it this morning before driving to work.
Do you guys think its this air/ fuel sensor is at fault or is it likly to be something else ie Lamba sensor?
Ive had a search but could find any pictures simular to mine or the exact same problem.
Thanks for you help in advance
