what are these codes : P1127 and P1129
I have got them few times after acceleration hard and then just cruising.
I looked from book and found
P1127 = Exhaust Now Warm, Downstream O2 Sensor
P1129 = Downstream Heated O2 Sensors Swapped
I have 100 cell metallic cats and Fabspeed mufflers. Also all O2 sensors are in their place - or are they "swapped" ???
