Hello, setting diagnostic monitors can feel really difficult. Here's an article on RepairPal: https://repairpal.com/drive-cycle-issues I would strongly suggest setting cruise control at about 57 mph for about 15 minutes or so to see if this helps -- make sure you have an open stretch of road you don't need to change your speed on.
