I hope someone has an idea of what is causing this. Anyway. during idle with the engine cold, the engine cuts out, usually going from reverse to drive, but it has done this when going very low speeds just above idle as well. I have the 1714 Superchips tuner and the airforce one cold air intake, with stock exhaust on the 2004 FX4 (5.4 engine). Any thoughts would be appreciated.

Try going back to stock programming and see if it still does it. I seem to remember a TSB about low speed stalling. I think there is a PCM update for it.
