Chugging, Black Smoke, No Power, High EGTS, Eventual Stallling Codes 1316, 0470, 1210
This has been going on since I bought the truck in late Oct. When I was test driving it, I did a run at WOT and it threw a CEL, which I assumed was an overboost code at the time. CEL went away after a couple minutes of driving.
I've noticed when pulling heavy loads that there seems to be a lack of power and it seems to puff black smoke. This isn't a constant stream of smoke, more like individual puffs as it goes down the highway.
This seems to be getting worse as time progresses, now its to the point where it will chug along with no power and the other day it stalled on me and wouldn't start back up. Sometimes it will throw a CEL and seem to go into limp mode when it chugs, other times it will not. The CEL is much more frequent when hooked up to a trailer, but if I get on it enough, it will come on unloaded.
I just got Auto Enginuity today and I'm getting codes 1316, 0470, 1210, and 1211. This truck does have some type of chip or tuner on it, though I'm not sure which one.
ICP is new.
I tried cranking it today and recording IPR duty cycle and ICP pressure. With KOEO, IPR DC was 14%. When cranking, it dropped to 0, then after cranking it went back to 14. I didn't start it, just cranked a couple times. HP Pressure went up to 2500, then 1600, then 1100 while cranking.
I've noticed some new oil leaks under the truck now that its cold, but the HP oil pressures seem to be fine based on what I've read and I don't have any oil loss when checking the oil, which was changed ~1000 miles ago with rotella 15-40.
The batteries were a bit low, so I've got a charger on it now and will do a buzz test before digging much further, what based on this info, what would you guys recommend looking into, or replacing to get this fixed?
