I am currently trying to determine whether or not I have bad injectors as well. I use Jscan and my fuel correction numbers are nearly the same. I did learn that those numbers are a measurement of acceleration per cylinder measured by the crank accelerometer to allow the computer to adjust the fuel qty to make all cylinders hit the same and thus balance the load to the crank per cylinder so that they are equal. ( also notice the unit of measure is in mass, not volume) It is not a function of injector wellness. Green Diesel enlightened me to this after fighting with jeep who could not tell me what those numbers meant. I am going to reach out to GD again this week and Jscan as well and see if they can point me towards the data the OBD spits out relative to injector condition. I just replaced the o2 sensor because a P2196 code but I did also get the over fueling code with it and my regen frequency has gone way up. I'lll ya know what I find.
