Will replacing the O2 sensor increase fuel economy?
I don't know when or if it was last replaced.
There is no service engine light.
So does that mean it is functioning at prime operation?
Just looking for ways to help this car run well and increase MPGs
2004 dakota sxt 2wd reg cab 3.7 auto 220,800 miles.
I got the car 500 miles ago.
