Re: Misfiring


I've checked & cleaned the TDC sensor, it appeared dirty but not exactly covered or piled high with anything so I cleaned it & replaced it with no luck.

I ordered a OBD2 code reader a few days ago and it has turned up today, It's showing fault code P0136, O2 sensor circuit malfunction (Bank 1 sensor 2).
I inspected the o2 sensor and found a faulty wire, it had been rubbing against speed humps & split a wire, I've repaired that & tried the engine again, Still no change unfortunately, Even the fault code is still present.

Would the O2 sensor cause these symptoms?
