Scanned system for codes and condition. Found a stored P0139 – Bank 1 sensor 2 oxygen sensor slow response code. Monitored scan data and confirmed operation. When sensor would be slow to respond the idle would fluctuate as stated and was a noticeable condition. This happened several times so we could confirm failure. Replaced sensor and cleared system. Test drove several times and condition did not return at this time.
