I recommend using a diagnostic scanner tool to read the engine fault codes. This will give you specific information about what is causing the strange noises. From there, you can research the code online or take it to a mechanic for further diagnosis.

Start by checking your oil levels and looking for any leaks. Low oil levels or leaks can cause strange engine noises. If everything looks good, consider taking it to a mechanic for a full inspection.

J

Before taking the car to a mechanic, try replacing your spark plugs. Old or faulty spark plugs can cause rough idling and strange noises. It's a simple and inexpensive fix that could solve your problem.
