2001 Jeep Wrangler mileage: 75,000. I read about the "knock sensor" that you have alluded to in answers to other questions. Does my model have one of these? I am experiencing extreme knocking when I use anything but premium gas! This has been going on for a long time now, but has really only hit home recently with the rise in gas prices. Would the knock sensor be the only thing that could explain this problem, because I have asked my mechanic before about it and they didn't mention this?

Your car may not be equipped with a knock sensor. Check the EGR valve. If it is not functioning properly, it can cause engine pinging.
