Hey, Jim (MNBoxster)... you probably know the answer to this question.
Since I'm replacing all four of my original 02 sensors in my 97 box with 94k on it, will I get better fuel economy? How about performance?
The PSTII tool showed slow reaction times on all four sensors and reeeaaaally slow reaction on one of them, which caused my CE light.
Logically, faster reaction times for the sensors should increase fuel economy and possibly performance considering the computer's in control of the car's air/fuel mixture, right?
