DIW: FIXD

When your check engine light comes on, you may immediately begin to wonder what's wrong.

The makers of FIXD say they can take away the guesswork.

FIXD plugs into the OBD-II port in your vehicle and says it will send diagnostic information straight to your smart phone. The OBD-II port is found in any gas-powered car made after 1996.

FIXD connects with a free app you download to your phone.

Does it work?

To find out, we enlisted the help from Lance Utz with Rusty Eck Ford.
