I am no expert, but I have done some diagnosis before. If I were starting with that kind of history and that many codes, I would write them all down for future ref then clear everything and drive it a little till you get codes again (probably wont be long). This way you can hopefully narrow down some of the codes that may not be from the cause of the problem(s).
Also, I would do an inspection of all the fluids and look for cross contamination.
I guess that would be the best start IMO.
Truck is literally not driveable, had to limp it into the shop.
No cross contamination in fluids, all of that is good.
Basically, at first my thought was wire chafing. But again, it all looks good from a quick once over.
My thoughts are that the injectors went (2 and 8) and was the problem for the initial problems. After continuing to drive, the EGR/Emission related components became clogged. Continued to drive, problem spread like cancer, putting it in its current condition. This would account for 0069, 0266, 0284, 0299, 0403, 0404, 0405, 0470, 0471, 0478, 2262.
However, the 2285 code for ICP sensor I have read that the HPOP's can leak oil onto the sensor and cause similar problems. Which would potentially clear 2285, 0284, 0266.
0113 is just because we removed the intake (I forgot I plugged in the solus after we removed the intake, it updated the codes then)
