On my 2005, I can show the engine codes by turning key on-off, on-off, on, and they appear in odometer display.

I second the ATF in the fuel. Knew someone who was told on a 6.7 all injectors were bad, was running real rough and blowing smoke. He pulled fuel filter which was filthy and filled the housing with ATF and dumped ATF in the tank, and within a few miles it was much improved and eventually engine was fine.

I have read the 6.7 injectors are made of tougher metal than the 5.9 as the pressures are higher in the 6.7
