Just had the PCV system totally replaced at 295K and had a new radiator installed as well.
But the problem is now that I got this done my full economy went from 28 - 30 mpg, down to 21 - 23 mpg.
Does anyone have any ideas as to what may be the cause? Puzzled and discouraged here. I figured I would have had an increase not the other way around.
Also, notice I get an A2 -315 code? Does something need to be replaced? If so, what? Where can I get one?

Thanks.
