    4.8's don't have AFM/DoD.

    Did you disable all the AFM related trouble codes if this is a 5.3?

    There are trouble codes related to the VLOM, so you will want to disable all those codes if you removed the factory VLOM.

    Setting all the DOD solenoid codes to 3 no error reporting will fix this.
