The Best Hit A Pothole And Check Engine Light Came On References. Once you’ve parked your vehicle, turn off the engine. If the gas cap is loose or damaged, this seal is broken and fuel vapor can escape.

It might take a little time, so give it a few trips to see if that was the problem. Any suggestions on how to fix this? And my check engine light came on i took it by autozone and i had the engine computer read it had 2 o 2 sensors that needed attention.
