If your engine has a fault you may notice a warning light on your dashboard. If your vehicle is not performing as you think it should come see us and we can offer advice.
Modern engines are monitored by sensors linked to a computer, and if anything is wrong the warning light is there to advise you to get the vehicle checked either to prevent a serious fault occuring, or rectifying an existing fault.
It may be that there is not a fault with the engine itself, it can sometimes be just a sensor that is in the process of failing or has failed totally.
