Firstly, check the spark plugs and ignition coils as they are often the culprit for engine misfires. If they look worn or damaged, it's time to replace them.

B

Next, inspect the fuel injectors for any clogs or buildup that could be affecting their performance. A fuel system cleaner can also help in this case.

M

If the above steps do not solve the issue, it's possible that there is a problem with the oxygen sensors or the air intake system. It's best to have a professional mechanic take a look at these components.
