Alright, I already know the answer to this, but I figured, "Why not ask the guys anyway?".
Coworker's truck. 2002 GMC CC/SB. 90,000-ish miles. Second owner, rarely gets driven except to pull a boat, and not in winter. Truck is a good runner, but is showing white/blue smoke after running a while and sometimes at cold startup. Has run an old Edge J/A almost its entire life.
Main fuel rate bounced between 7.8 and 8 at idle, so thats not a problem. CP3 held rail beautifully, right on desired. Smooth idle. Was NOT smoking while we did our tests.
Rates:
Cyl Idle Drive
1 4.1 7.2 (and climbing as I watched it)
2 -3.9 -5.1
3 -0.9 -2.6
4 0.8 0.8
5 1.3 1.9
6 -4.1 -6.3
7 1.2 1.3
8 1.7 2.5
I told him to start thinking about buying a set of injectors, as 1,2 and 6 are going/gone. Gave him Lincoln's name to buy them from.
There's nobody in the mid-Michigan area that I trust to service a Duramax, so I told him if he buys the parts, we can do the job together.
*sigh* I hate LB7 injectors.
