Why is this Z3 Roadster misfiring?
BMW 1999 Z3 Roadster 2.8, misfiring on cylinder 4,5,6, and also random misfire. Have changed 3 out of 4 lambda sensors, changed all the spark plugs, even tried clearing the faults from the memory and swapping ignition coils 1,2,3, for 4,5,6. The MIL light does not come on but the codes came back as misfire on 4,5, and 6. It is running ok untill the engine gets warm and you try to boot it then you get the most awful misfire and a complete lack of power. There is also a strong smell of petrol sometimes. Could you help please its driving me crazy!!!!#post165366
