Ken, I found out yesterday that my Dakota has a problem code P0172 "system too rich on bank one". As I think I understand, that is the side that has the number one cylinder in firing order. To me, it makes sense. Correct me if I am wrong, but not enough o2 is mixing with fuel, not enough torque is being produced on the downstroke of the Pistons, this would equate to sluggish / non responsive acceleration, if I have the sensor replaced which is down on the bottom left side of the block, have all vacuum hoses checked and have mass airflow sensor cleaned. Do I have a good chance at this fixing my issue?
