First, check your spark plugs and ignition coils. These are common culprits for an engine misfire. Make sure they are clean and not damaged. If they are, replace them.

It could also be a fuel injector problem. Check the fuel injector for clogs or leaks. If you find any issues, replace the fuel injector.

L

Another possible cause is a vacuum leak. Check all hoses and connections for any tears or holes. If you find a leak, replace the damaged part.
