I got a Toyota Rav 2014 and i just found out that I have a bad O2 sensor problem

What is your question?

then a wire burnt out near an ignition and beacause i live in the UAE and american parts are hard to get here im putting off on doing the sensor how ever im having troubles like u cant imagine first of all my car has lost a lot of engine problems but my main concern is that everytime i put the car on N and shift it to D the cars seems to jump as if there is a gear problem then tiptronic gears dont seem to be working everytime i switch to sports the dashboard dont even change from D to 6 5 4 3 2 1 can anyone be off asist
