Keep getting these fault codes.

8F - DM-TL leak detected
FA - Functional check pruge valve
F2 - misfire cyl #5
F1 - misfire cyl #4

Car is running fine, decided to check the codes for fun and these keep coming up even after I reset them. Changed the fuel filter about 1,000 miles ago. Just got back from a Vegas trip, all highway and not one sign that anything is wrong.

Any clues?
