Frustrating.
Ok I have a a 2006 Expedition 5.4. It runs fine but when the engine warms up it has a significant power drop. Foot to the floor it won't accelerate until it hits about 3grand then it takes off like a bat out of hell. Park it in the driveway and when it cools off it runs fine until it warms up...- ChrisC73
