he code shows the 02 sensor in front of the muffler. The car is in the shop they replaced it a third time thinking it was faulty natch of 02 sensors. Checked all wires all were good. I wastold it is showing a flat line to this sensor and the shop is going to replace the computer? Could this be the problem? This is the second shop I have the car in.
