I have a 2008 Ford Expedition King Ranch. It starts fine and drives fine for awhile, but when I slow down to idle at a stop light or go to park the engine will all of sudden start shaking and sputtering. I dont get a CEL or anything. The engine then dies or I shut it off. I can then restart it and it runs fine. Any ideas whats wrong with my Expedition?
Engine Shaking and loss of power
Had a slight 5.4 Engine shudder at idle..,,Used some gas line antifreeze (methyl hydrate) and that fixed it. There was a change in weather which nay gave caused a moisture buijd up in tge fuel tank. Also why pilots keep their Aircraft fuel tanks full, in order to reduce condensation
Make sure your battery connections are great not just good
