Hi, my "check engine" light came on suddenly yesterday. When this happened before, they said I didn't tighten the gas cap all the way. How can I test this, to see if it corrects the problem? Can I just unscrew and tighten the gas cap now, or do I have to put more gas in and drive it for a while? Thank you.
have the same problem?
