Cylinder 3 and 4 misfiring spark plugs good coils

Hello,

The misfire you are experiencing, could be due to an issue with the fuel injectors on those two cylinders.

Take a look at this guide, it covers on how to test the injectors:

Go thru the guide and let me know what you have found.

Please let me know of any questions.
Thank you.
