Ok I have the error that points to the upstream air sensor. I am on my 4th one in 2 weeks. The reset lasts less than 4 miles before the check engine light comes back on. I have gone to a couple of the local big box parts stores in Clemmons, and they have been less than no help I have reset the obc2 by unhooking the battery, and I have done the odometer reset trick as well. The sensor is good, so what is the actual issue that is causing the error.
