It's programmed to inject more fuel while warming up. I don't know if you can disable warm hold function with PTT, but you can try making sure that the cruise control is on and then using it to barely bump up the idle. I don't know the exact reason why they are programmed this way, but I think I remember it having to do with getting moisture out of the system quicker. Installing a new DPF and fixing any codes is what I would do.
