A close friend of mine has been having a nightmare with his 2003 Ford PS. In the first 50,000 miles it was in the shop 48 days! Seems most of the problems are fuel system related. It will have awsome power sometimes and then out of the blue it runs like a old 6. 9, smokey and almost no power. If it is under 60 degrees sometimes it will hardly start, lots of white smoke and it shakes as though it is only running on 4. Next time it starts fine? He lost a rear main seal and after geting it back from the shop it hydrolocked the engine and they tell him at least 3-4 weeks to get it back. He is in the process of trying to enact the lemon law but Ford keeps throwing up road blocks for him. I feel for him, it seems everything that could go wrong with this engine has gon wrong.
