I've been having problems with my car recently. How can I tell what's wrong with it?

First, you should check your car’s manual or consult a mechanic to determine the cause of any symptoms that you may be experiencing. You could also take it for a test drive and observe how it performs in different conditions. Additionally, if possible, record data from the vehicle such as engine performance, fuel efficiency, and other diagnostic information. This will help you better understand the problem and make an informed decision about what needs to be done.
