Those codes are all o2 sensor codes and I see you replaced them. Too bad you don't have a scanner to show you live data and graphs. The issue is it is all common to the o2 sensor circuits. I would check the wiring for any frays or damage around the cord going into the fire wall. Check connectors at the ECU My suspicion is a faulty ECU which you may find a good used on at a local wrecking yard. Without putting it on a scanner thats what your facing .
