The Engine is the power house in your vehicle. Your engine uses internal combustion to generate the power needed to move your vehicle. When your engine is not running at maximum efficiency, it can greatly reduce power and driveability. Your on-board computer is constantly monitoring input from dozens of sensors. When it detects something not operating within parameters, it will turn on your check engine light. A special tool is required to obtain code information from your computer. If your check engine light is on, come see us for a diagnostic!
