no, they always fluctuate. different cylinders burn at slightly different efficiencies and this will produce variations from one bank to the other, could also be minor exhaust leaks. as long as both read within their specs you are fine
O2 sensor question
Hello All,
So my x threw a cel for low functioning O2 sensor Bank 1 Sensor 1. Which can be seen in the first pic.
I replaced the sensor with a Denso unit. I expected the readings to become somewhat equal, but they are not as can be seen in the second picture.
I guess my question, is should the readings look identical? Or will there be variation as is what pictured. The green line in both picture is the one in question.
