But it did show a very similar code 2384 with 4 counts. Go into Cummins Insite and click the "help" menu and go to "fault tree index" and type in the 2 codes if you haven't already ran down troubleshooting these codes. That control module is VERY temperamental and will cause all kinds of running problems and fuel mileage loss, high EGT's, low boost, fuel knocks, weak ir none existant 3rd stage jakes, all kinds of good things with the cm870's. It is an air operated system after the control module so there is no active feed back if the turbo actuator is in the correct commanded position. Meaning if this leaks air or is faulty in any way, the ECM has no idea where the turbo VG ring is.
Im not saying this is the cause of your rough idle, but it may very well solve some issues that are happening that you may not know about and also save your engine from further abuse and for sure a tortured overheated earlier death.

Make sure you follow the tree for the signature and ISX cm870. The ISM cm870 an cm570 appear to have electronic actuator's that your engine does not have.

Also clear out all those inactive codes now that you are aware of what they were and you have done extensive repairs. Some of them can be caused by what you've done and some can be from past owners problems he may have fixed. Clear them and monitor if any come back.

Thanks man, i appreciate you taking the time to guide me trough this and for everyone else as well.

so last friday when i was moving the actuators around on the ifsm, one of the little bolts snapped of into the ifsm ;(.... :/... yesterday i tried to extract it but screwed up n chewed up the housing a little. so the shop owner is giving me a used ifsm housing for $100, isnt to bad in my opinion. just gotta wait for this rain to clear up so i can get back to the truck and work on it.

so ive looked up the the 2 codes and since i dont have that control module? " shouldn't i have it?" could it be the ground that is hooked up to that needs some cleaning? or it could be my entire engine harness needs replacing, which could be a possibilty since it has 1.3 mil miles on it.
