Thing is my car was perfectly working before going to the tuning shop so I do not think the dealership did a wrong installation as I remember seeing him hand tight the sensors then use a wrench to torque it. Could o2 sensors break on a dyno due to heat or vibration transmitted to the car from the tow straps?
