I just hooked up my new Scanmaster today and did some quick passes on the interstate this afternoon. Why are my o2 millivolts just jumping around and giving me seemingly randoms numbers at every update? They never steady out at any speed, including idle, and the only time I get what seems to be an accurate reading is when I read the recorded pass results. FYI--I'm running a brand new heated o2 sensor.
