six injector issues

[shawn46996]

changed #6 injector with a new one from peterbilt and still have a miss and leak. # 4,5,6 all run colder than the from 3 cylinders. #6 is running 150-200 degrees cooler. #4 is around 50-75 degrees cooler #5 is 100-150 cooler. i swapped the mettering solenoids around thought that was the issue but still same thing. i did the injector leak down test with the starter i get all kinds of bubbles but can't get them by manually turning the motor over. have you saw brand new injectors faulty or am i just the lucky one.
