Question: why is check engine light on

the check engine light has been on for about 3 weeks now,but the car has been running ok. i just changed the oil yesterday and put gas treatment into the gas tank and went to the gas station and filled up the tank. when i finished gassing up i went to start the car and it started turning over real rough and would not start,also the gauge lights were all on. i pushed the car into the parking lot and opened up the gas cap,then put it back on real loose. the car then started right up? what kind of problem do i have here?
