Hello,

I have 1997 528i w/ a P1189 code stored. Engine runs rough when cold. Gets better when it warms up, but still has rough Idle.

It says Bank2 sensor 1

Any ideas would be helpful
Thanks,

John

when I had a 1997 e39 I had the same error, and from memory I believe replacing the pre-cat o2 sensors fixed the problem. I think this had something to do with the air fuel mixture readings???
