Broke down yet again

Latest is that the wiring to for the aftertreatment to the ECM was split somewhere.

Bought the IMAP and EGR Diff pressure sensor, the Exhaust backpressure sensor was replaced already when they did the EGR valve. Having them take the intake off and clean it out as well. I pulled the crossover tube a couple months ago and cleaned it, Just don't have the tools on hand to remove and clean the rest since our house is that Freightliner. Hoping this will get things going into a better direction.
