The wiring harness inside the driver�s side fender rub and short out, usually causing Transmission Mode switch failure but in your case may be affecting O2 sensors & ECM
Further if 3 of 4 O2 sensors were indicating problems, I would look at the other end, that being the MAF Sensor- Air Filter- incoming air.
