P0130 issue on BMW Z3 M44

[Kenya]

Dear friends,
I have P0130 error for my BMZ Z3 1.9L M44. I replaced O2 sensor but the issue is not resolved. The voltage stay at low and 0.1a and a short FT is higher at 25%. Recently, I had a DISA maintenance but after it, STFT looks ok but will double check air leak just in case. No engine check light is on. I am wondering a circuit error is something wrong in the wire cable from the O2 sensor to the engine. Can someone advise me how to replace the wire and what is a part number?

regards,
Kenny

After long driving, O2 sendor started working. It is 0.3A to 0.7A range. The Long Term FT is 8% and STFT is -1% to 2 % range. Looks ok, however, Ignition timing not stable at the idele. It is between 5 degree to 16 degree. Last time, I remember it is around 4.5 degree at the idle. What cause the fluctuation and how we can fix it?

Regards,
Kenny

Timing fluctuation has to be a crank or cam position sensor error. Check for codes again.

Thanks! Yes, I had P0135 and P1174 while it can be cleared. Will check the sensor.
