Is your check engine light on? Are you wondering if it is something minor or if your vehicle is on the verge of blowing up in traffic? If you are unsure about going straight to the mechanic shop to get charged over $100 just to plug in their scanner to tell you why the light is on? While I do not encourage anyone to drive around with their check engine light on, for $10 I will use my scanner and tell you the code so you can know why the light is on and decide what you want to do.
