I understand from a bunch of posts on the Ford site that they are having a major problem with something they call "CACKLE". Seems to be a poorly engineered high pressure injections system that is causing their engines to sound like all H*ll is breaking loose and their MPG goes into the toilet. Their stealer's say when they bring them in that they don't have a problem. Anybody here know what is happening to the PSD? What internal engine problems could this cause to the PSD?
