CM 871 Injector Issue

[graysonlogistics]

Ok so I moved the timing actuators and ran the cylinder test again and the front bank failed, it didn't follow.

So I swapped #3 injector with #1(which is new) ran the overhead set and fired it up. Still ran rough. Did the cylinder cutout and it ran on #3 this time and Did NOT on #1....
So I pulled the #1 (which was #3) injector out made a mad dash to MHC Dallas and got another injector.

Replaced it and fired the truck up and after the air cleared up we had smooth idle.

Ran cylinder test again after the coolant reached 140, all passed eventually.
#3 pass immediately #1 and #2 teetered fail/pass for a few seconds then settled into pass.

Thanks Hammerhead and Rawze for all your input.
