97 Jeep Grand Cherokee computer not ready for smog CAT EVAC. No CEL 1K miles

Hello, EVAP stands for evaporative emissions system. Make sure you have between 1/4 and 3/4 a tank of fuel for this to set, and drive normally. For CAT which stands for Catalyst, you'll need to ensure you have the right amount of fuel and drive it steady at about 57-60 MPH for maybe 15 minutes -- and it should set.
