If you live near an AutoZone they used to offer free check engine light diagnostics.
See what code they can retreive from the computer with their device and check it against the list of codes. It may not just be a missing Gas cap code. There are hundreds of codes computers can return.

Call your parts department at your local Hoda dealer and give them the serial number. It's usually a four digit number.
