cylinder contribution issue

Have a code for cylinder contribution for Cylinder 2 and 4 on a 2015, 1.8 liter Hyundai Elantra. Also, just on 4 is a misfire.The data shows 2.5 Ms injection time except for Cylinder 4, it shows 0.8 Ms injection time. All new fuel injectors 2000 miles ago. Power contribution codes for 2 and 4 has been on for about 500 miles.Checked connections and cleared the codes and they came back. Could the fuel injector timing on 4 cause the other cylinder contribution issue on Cylinder 2, given the firing order is 1,3,4 and 2.....would a new injector on 4 have a chance of fixing the issues or do you see something else?
