Well when I started the car the cable pulls open and stays open, then I got the car to 5k+ revs and the cable didn't move? A lambda plug was put in. My mechanic friend said because the rear lambda is suppose to read clean air it would outside the exhaust, so if the cat was broken the code would be gone for the bank 1 sensor 2?? I have no idea about mechanics, I'm a welder by trade so I'm learning as I go along. The car has done just over 70k miles so it's a fairly good car except this f"""ing electrical issue haha
