CM871 kickin my Butt

[RustyWood]

Hi Guys
So just over a year and a half ago, I bought a 2009 Kenworth T2000 with a CM871 at 624K miles, and started my researching what I could find to learn about this engine before I put it on the road. I'm an old hot rodder car home mechanic, so I'm only just learning this Big Truck.

I quickly and MOST appreciatively found Rawze's Videos on YouTube and this forum of his and did the full EGR Clean on my Truck before putting it on the road. Replaced IMAP, P-Diff, pressure washed everything from EGR to Intake and baked them good. Man did she run Great for awhile and I attribute so much to Rawze and his knowledge on this engine for me doing great thus far as I had no clue of these Big Diesel's.

I don't Idle if I can help it, and I've been doing 15k mile Oil changes with Rotella to keep the Soot levels to a minimum and my Truck is completely Stock with all emissions garbage in place.

I live on the Idaho Side from Spokane Washington, so I'm very far away from Rawze and a lot of you experts, so I'm kinda on my own to fix it as I've not had much luck finding a good shop around here.

Anyway, my Truck started running like I've lost some cylinders. I had a shop run me up $5609. and replacing Turbo which I verified the VG plate frozen, and they did Injector #3, but finally put their arms in the air with no idea's admitting they didn't know Cummins that Good and it's still running like crap.

I've watched the Cylinder Cut out Tests so I ordered but still waiting for my Diagnostic Cables Set with Insite.
I'm at 713K now, and I've taken all 4 Fuel Actuators apart, they are still painted RED, but weren't too dirty inside, and 3 have 3.4 deflection on dial indicator, 1 was about 2.2 I cleaned the shafts, put back in and still running like crap. Upon seeing the Video of an IMAP full of crap again of the guy who'd only done 80k since his replacement, I removed mine and found mine and the EGR track of good'n'plenty quite loaded again with soot only going 90k on my truck.

But here's the thing, and I greatly appreciate any of you helping me. I have disconnected from the EGR and line from Intercooler to Intake Air Horn, removed Air Horn to Head and started Engine with the rectangular intake Opening at engine open, and I can still tell engine acts like it's down cylinders. I don't have diagnostics ability yet, but wouldn't this mean it must be the Fueling Actuators, either a timing or metering ??? Also, I'd like to pick 2 new ones up but even Cummins website shows they are not available now??? Is this what you guys are seeing, are these dang things not available anymore ?

Thanks in advance for any help guys, and thanks Rawze for all you've put out there, many of us would be no where without your Videos and Info.
