Fuel injector testing video

I took video of the spray patterns on all 6 injectors. The video's order is 6 to 1.

I know the spray pattern is off for all of them. Do you think a cleaning will help or should I expect to replace them all?

Look OK to me. If the engine is running nice and smooth, then I'm not sure why you're thinking there's a problem with them.

The engine seems to be a little rough and I was getting a strong unburnt fuel odor from the exhaust. I thought maybe the injectors were leaking or something. I pulled the plugs for inspection too and they looked great. Now I'm suspecting a valve or two is out of adjustment on the passenger side. I had my mechanics stethoscope on the driver's valve cover and it sounded smooth. I put it on the passenger's cover and it was deafeningly loud.
