And no boost is indicative of something not right for those 5 or so miles. 12 pounds of boost is about max for a stock 7.3 motor with no tuner as is 1200 F for EGT.
Possible you have a Exhaust Back Pressure valve that stuck or the tube that is used to sense the EBP could be clogged. Do you have any codes on the ScanGauge? (above the rear view mirror in your van if it is in the same place Robb had it) . That might give you an idea of anything that threw a DTC.
What happened to necessitate replacing a bank of injectors? Did they do the Glow plugs and under valve cover harness while in there?
Haha... itís funny you point out where my scan gauge is...lol.
I didnít think to go through the scan gauge at the time. I was literally just bewildered at the fact I was doing 25...
I had one bad injector and just had them replace the bank... didnít do glow plugs because the advisor didnít recommend.
Those are great points and Iíll bring them up with the tech tomorrow in Lincoln,Ne.
Thanks for the advice
