OK, I had a similar problem two weeks ago. I had a major power loss, and codes for #4 inj (0204), over boost, and 2149, but that somehow related too.
I took it to my dealer, the exhaust brake wasn't working, needed a new vac pump, imagine that! They bone heads fixated on the pump, never did anything about the codes, even after repeated prompting.
Last time it fixed itself, just cleared up and worked for 8-900 miles, a whole week. Started doing it again on my trip back to MN for Christmas. This time I have more codes yet...
2149, group 2 inj harness
0304, #4 missfire
0303, #3 missfire
0300, multiple missfire (smart computer!)
0204, #4 inj wiring
0234, overboost
Last time it started working fine with the Quadzilla still hooked up. This time I disconnected it. It seemed like it wanted to clear up but didn't.
Feels, sounds, drives like I am on 5 cylinders, sucks!
No fuel smell in the oil, which I freshly changed last night. If fuel was leaking, it would smell, I drove it 60 miles like this just to reach some sort of civilization!
OK... open to any and all advice. I am hoping the truck fairy will come tonight and it will self fix again. In case that fails... ???
