Does Illinois have a mileage exemption? In Pa and some other states vehicles driven less then 5000 miles a year are exempt from testing and get a exempt sticker.
Drive cycles are pretty much manufacturer/vehicle specific this is why service info is critical today here is a example from the NJ emission site>

Rule of thumb Asian cars are pretty easy to get to complete then domestic and euro the hardest.
Most if not all will take overnight and a cold start for evap and fuel level is critical, some actually run evap after the car has been parked several hours and temps are equal to ambient. For this reason most if not all states allow 1 monitor to be incomplete and still pass.
