I thought the o2 sensors wiring and the wiring from the tps might run along with eachother some where. And that possibly something rubbed or somehow removed the plastic over the wires exposing them to eachother, causing the car to malfunction in each place that the wires corrosponded with. Since the o2 Sensors came on at the same time the power mode started happening, that is why I thought the two were connected.

As I pointed out way back in the thread, the TCU is now the most likely culprit. Don't hack any wiring about until you have tried the used TCU replacement AND do not rule out the prospect that this also could be faulty. I hope you are sure it perfomed properly during its earlier history. Fault finding by way of substitution, requires caution in this respect.
