I was a truck mechanic before I retired. If we had a problem like that, that was hard to find ,we would hook up the diagnostic computer, and drive it under the conditions that the problem occurred. One driver, one laptop man. You don't just look for fault codes to occur, you watch parameters:you look for readings that are wrong for your engine load situation. For example-the engine coolant temp reading can affect the PCM's delivery of fuel; the boost reading,intake air temp,fuel pressure,egr position, and so on. You know the engine is under a load, so your readings should be in a certain range. It's at idle so a different range. Sensors can fail 'in range'- in other words the PCM thinks the engine is not under aload,when actually it is. There can be mechanical faults that don't log a code, but if you load test with the laptop hooked up,you can find,and FIX,a lot of problems. Mark.
