Welcome! My name is ***** ***** I will do my best to assist you with this problem.

so coil and plug for 1 was changed and same issue ?

is it a dead slip at idle or when driving ?

Customer: replied 29 days ago.
It idles fine it stumbles a little on acceleration

at this point the odds are the 1 injector is restricted and or bad

its best to swap 1 injector with cylinder 2 and see if the skip moves the odds are it will and then you know the injector is bad

Is there a video or some instructions on how to replace the fuel injectors on this engine?

the intake manifold has to come off then fuel rail is lifted up to remove the injector
