I bought fuel injector from Amazon. Installed them but one was faulty and continued to dump fuel. Code P0306 and P0175. Noticed raw fuel coming from exhaust pipes. I've reinstalled my old injectors and replace spark plugs but still have engine knock

Can you please shoot a quick video with your phone so I can hear the noise? that way I can tell for sure what's going on.

P0306 - Cylinder 6 Misfire Detected
P0175 - System Too Rich (Bank 2)

I would remove all fuel injectors for testing, this guide can help.
