Unhappy 2016 Buick Regal Turbo Engine issue

Hello, I am having an issue w/ a 2016 regal turbo, it had been idling rough for a month or so now. Cleaned the throttle body, didn't help. Had no active or history misfires on any cylinders. Changed plugs for the hell of it. Nothing seemed to fix it. I FINALLY got a check engine light(General Misfire code) and seen cyl 4 having multiple missfires but only at idle. When its above 1000 rpm its fine. I swapped cyl 4 and 1 coil packs, didn't fix it. Cyl 4 still had misfires at idle. Fuel pressure seems good, I didn't check compression yet but im leaning toward a bad injector? I did the average fuel injector pressure calibration on my snap on scan tool and it seemed to fail when it got on cyl 3 and stall the car out completely....

Has anyone had any issues like this?
Next question any good information on how to replace the injectors online?
