Wait, you paid $340 for a kit that just squirts mystery fluid into your fuel rail? That's like paying a fortune teller to diagnose your truck. Those tool truck guys could sell sand to a camel I swear. Good on you for actually pulling the injectors and finding out the real problem, most guys would just keep dumping money into additives hoping for a miracle. Common rail injectors are way too precise for some cleaner to magically fix worn out internals, once they're toast they're toast.

Kept making that same mistake for years until I stopped trusting auto ISO in dim rooms completely. Now I set a minimum shutter speed in the menu before I even walk in the door, usually 1/125 for people, and I just let the camera push ISO as high as it needs. Yeah the shots get noisy, but a grainy photo of grandma laughing beats a blurry smear every time. The other trick is just to raise your ISO ceiling way higher than feels comfortable, because modern cameras handle 6400 fine and you can clean up some of it later. Locking the shutter is the whole ballgame in low light, the rest is just noise you can live with.
