Test the exhaust port temps for a cold cylinder indicating incomplete combustion from either low compression or a faulty injector.

If a cold cylinder is found since this is post in frame, swap that injector with another cylinder and see if the problem follows. Let me know. We can follow up as needed.

Please take a moment to rate as that is how the site credits my time helping on the site or let me know if you need more help. 5 star and bonuses are always greatly appreciated.
