Replaced O2 sensor----Does computer need a reset?
In the hopes of improved gas mileage, I changed the 02 sensor to a new AC/Delco. At 95k, the original sensor was shot. The tip was coated with black carbon, the sticking EGR valve probably was no help!
Do I have to reset the computer or just drive as normal?
Also, interesting that AC Delco has changed the design of the AFS109. The tip is now a perforated cylinder. The old design was a spiral slotted bulbous shape. I called AC Delco and confirmed that the part I recieved is genuine and of current design.
