hey guys so everytime i go get gas with my car, the service engine light comes on. goes off after driving like 20-50 miles and then comes back on next time i get gas. anyone have a clue on what this is? need new gas cap is what ive heard but im not 100% sure

 

Are you leaving your car on while you pump gas ?

 

nope, always turn it off. light turns on no matter how much i put in too, turns off in a day

 

best guess with out codes from light would be a gas cap

 

yeah that's what i figured, thanks
