1998 Ford Expedition 6 cyl Two Wheel Drive Automatic 136000 miles
My epedition hesitates at times. I took it to the shop and they hooked up to diagnostic computer and told me the history shows the knock sensor is not working periodically and no need to fix it until it gets worse, because it is an expensive repair due to its location.
What does this sensor do and can I be sure the sensor won't just fail completely one day and leave me stuck in the middle of the road? How will I know when it is time to get it replaced?
have the same problem?
