Stalling in cold temps
Hello, I've tried looking for this particular problem but having no luck. I've got a 2012 Expedition EL Limited 4x4 with the 5.4L 3v. It has started a problem when the outside temps are below 40°, the truck starts and idles fine, until you let off of the brake. Then the engine stalls. Put it in Park or Neutral and it restarts immediately, idles fine until you try to take off again. It will sputter when you give it gas, and after you get going it will run fine until you come to a stop. Have to drive 2 footed to keep it running. It doesn't give a CEL and any time. Once the engine is warmed up, temp gauge rising, the truck runs fine. It doesn't matter if you start and try to take off right away or wait several minutes. At first I thought it was an IAC valve, but then found out this model doesn't have one. So far, I have cleaned the throttle body, MAF sensor, used Lucas fuel injector cleaner in the tank, and checked the air filter which is a little dirty, but not bad. If the ambient temperature is above 40°, the problem doesn't happen. Has anyone had this particular problem?
