Low acceraltion bucking and jerking. Put it to the floor and it will snap your neck. Bad accelerator position sensor. Only on drive by wire cars 2005 and up. Parts places only show the part being on 2007 and up but they are wrong. Ford started using the drive by wire system in late 2005. We never thought to check it. Replaced everything but this part that supposed did exist on my 2006. Hope this helped someone.
When im driving acceleration is slow and on the highway when i release the throttle it kinda jerks
