Cm870 demandated hot egts

[Upnorth83]

It’s was auto correct on the oil cooler. It’s actually a {after-garbage brand} cooler. I changed to that because the original broke. I’m not trying to blame the engine I’m trying to keep it going so I don’t loose my career. Before the demandate i had so so many egr valves fail and at 1000 dollars a piece I couldn’t keep doing it. I wasn’t trying to upset you. I’m just trying to ask someone that I believe is very knowledgeable about these problems. I can turn nuts and bolts and trace wires, rebuild engines, but I lack in the programming and computer skills end of it. I’m a one man show. I drive, repair, and run the office. I had 12 trucks not too long ago and recently sold everything and kept one. I love my truck. Everybody keeps telling me to just get a new one but I have a lot of blood sweat and tears in to this one over the past 10 years. I recently inframed the engine. In doing so I replaced everything. From harnesses/ sensors to rocker arms and front case gears. I’m wanting to learn how to identify and fix the problems I have in the ecm tuning. I guess I’m mainly asking for help making sure I’m on the right track with the calterm and insite and if once I have acquired them if I could get you to help me learn and fix my issues.
