It's possible that there is an issue with your engine's timing chain or bearings. It's important to take your car to a certified mechanic for a thorough inspection and necessary repairs.

If your car has been sitting for a long period of time before starting, the knocking noise could be due to oil not circulating properly. In this case, try revving your engine a few times before driving to see if the noise goes away.

It's also possible that there is a problem with your fuel injectors or spark plugs. Have these components checked and replaced if necessary to ensure your engine is running smoothly.
