First, you need to identify the issue that is causing your car to malfunction. Check your engine light and any error codes that may be illuminated on your dashboard display. If necessary, consult your vehicle's manual or take it to a qualified mechanic for further diagnosis. Once the issue has been identified, you can then proceed to try and resolve it yourself by performing basic maintenance tasks such as checking the air filter and spark plugs, cleaning the fuel system, and replacing worn out parts.
