Makes sure you have between 1/4 and 3/4 tank of gas for evap. It will run overnight after driving. For O2 I usually do 5-10 miles at highway speed, no faster than 60 mph, then do some stop and go traffic. That’s how I get all the monitors to set. In PA you only need 7 out of the 8 to set for you to pass the emissions test so focus on the O2 sensors rather than the evap
