so I went and tried an injector balance test to see the state of my injectors after a couple codes popped up and went away. got some strange results and i'm sure I'm doing something wrong. I see that numbers should be + or - between 0 and 10.
balrcyl1 - 217 mm3
balrcly2- -1919 mm3
balrcyl3 - 1347 mm3
balrcyl4 - 2046 mm3
balrcyl5 - 1312 mm3
balrcyl6 - 817 mm3
this was at 1800 rpm at 47 mph
I have no idea whats up with these readings
Check at Idle and if you have an automatic also in Drive with your foot on the brake (not moving forward)
Tried that. About the same result. One said 1 for a few secondsQuote:

You have injectors going out. The +4 is shot and the +3 isn't far behind.Quote:

Also keep in mind; EFI Live balance rates logging will show you the Cylinder number, BALRCYLx, based on Firing Order which is 1-5-3-6-2-4 for the 5.9 Cummins as viewed from the front of the engine.
Here's an example; BARCYL6 is the 4th cylinder from the front.
Yeah I knew they were bad as soon as I saw the results. I do have an auto and that was in drive with my foot on the brake. What blows is the truck runs perfect and doesn't smoke.
What are the numbers they are reading when testing the injectors? I have 3 that read high I have a 4, 3 and a 2.5
