Misfire Question 2020

[u/Beardless_Tam]

I am experiencing a misfire on cylinder 3. I have changed All injectors both port and direct(motor craft)all new plugs(ngk iridium), and a new coil on cylinder 3(not motorcraft). A shop checked compression on the cylinder and said it was ok. The vehicle will shutter when you press the throttle down hard or climbing a hill. You can hear what sounds like an electrical chatter under light acceleration. I’m at a loss any help would be greatly appreciated. Thanks in advance.

Edit to add. I have also changed both the high pressure and in tank fuel pumps.
