Since this is a 3800, with only one O2 sensor controlling F/A mixture, all injectors should be commanded the SAME pulse-width.....four of them are way off.....
Do you have misfires on 4 cylinders? Have you looked at misfire data on a scan tool?
Have you taken resistance readings on the injectors? Should be around 12 ohms on a cold engine....
