Odd that it would be a misfire code... I mean, 02 sensor I could see... Whats the code?

Interestingly low mileage. Though, I doubt the car is throwing that code just to screw with you, lol. If its misfiring, see if maybe the plugs are covered in oil, or maybe fuel as you put the new injectors in... Maybe one of the injectors isnt even firing.

it's most likely mal-tunning, Your injector is not firing properly. Make sure there well grounded, test each one individually. Check for fuel as well as pulse.

Im leaning on a lean AFR causing knock. Injectors are straight foward I mean in the Evo you dont need to splice the clips in them either so I would guess they possibly pooched the tune. AFR may tell the story
