Most likely you should startwith Air Fuel Sensor. Twice the cost of the oxygen sensors but they do twice as much. The P0158 is for the rear oxygen sensor and may not be faulty. A scanner would be able to determine the overall condition.

Thanks for your answer.
Do you think its not recommended to drive at all? What is the impact on the car, if not fixed for a little while? I dont see any difference in driving.

You are most likely damaging the catalytic converters. Very expensive, definitely over $1,300.00
