everytime i get gas engine light comes on thereafter
2 weeks after getting the vehicle, got the same problem. Turned out the cap was good, just needed to be turned a couple of times. Now I crack the max out of the cap and it hasn't happened since.
Check engine light will illuminate when gas cap is not properly sealed.
