what is the engine ser#? (ESN #)?

What year, make model truck? type of operations you haul, some more history.

Is it egr-Deleted? (De-mandated)? and if so, by who?

some background / history, etc. always helps.

none of what you describe as problems sound normal at all for issues typically seen in an ISX .. but more like severe abuse or possibly bad custom tuning or bad delete programming. That or someone not knowing what the h#ell they were doing when it was rebuilt... Possibly aftermarket parts, etc.

you gave no indication what year or type isx it is. If its a newer model...
(2011 and newer engine model Common rail ISX's)...
Has anyone checked the injector trim codes to see what cylinder the injector belongs to?... you said it could have been swapped around. - I hope someone set the injector trim codes to match this if they did. You can also look on quickserv to see if it is an original injector, what hole it belonged to. - Quickserv is free (cummins.quickserv.com) so you should go sign up to get all info about your engine and all manuals, etc. if you have not done this already. If it is a common rail model ISX, look at the inejctor trim codes in Insite. Look at the injector trim codes on the injectors themselves to ensure they match up per cylinder, and then look on quickserv to see if that is where they originally were when the engine was built.
