ive been getting this for about a month now and i dont know what it is. i got it after pumping gas. started the car and the CEL pop on when i got on the road. its been on scine then.

I did not leave the gas cap open/loose.

anyone have this problem? if so how did you fix it.

 

sounds like you need to get your evap emissions system checked out and maybe its not your gas cap...
