We had a similar issue with one of our F-550 trucks a few months ago. 6.0 liter ('06 or '07 model...). There were a few other symptoms as well....idle speed would vary when the left turn signal or hazards were applied. The engine sometimes would die when the high beams were turned on. Basically, we could get the engine to die or change idle speed just by messing with the turn signal lever (multi function switch).

We replaced that and our symptoms haven't returned (yet).
