    Starting when I bought this car used with 37000 miles on it I get a check engine light the code set is a loose gas cap and has now occurred 3 times in the last 9000 miles. I know that the cap has been reinstalled properly after refueling and I have to bring the car to my mechanic to reset the engine light, the cap is loose when the light comes on.
