I have a 2003 Dodge Dakota with a 3.9l V6 with 215,000 miles. Recently was playing with my new scan tool, and looked at the live data, and both banks are adding fuel on the long term trim.  But bank 1 is a lot higher than bank 2.  Is there a reason that would cause this, and how can i bring them closer together.  The truck does not have any engine codes, and runs really good.  Just saw that and was curious
