My expedition began stuttering or shuddering and I took it into my local Ford dealership. The car still has a powertrain warranty, however, the problem they said was a faulty ignition coil. They said it was the number 4 coil and were going to charge me around $350 to fix it. We bought a new coil, however, now we are not sure how to tell which is the number 4 coil. We cannot find a diagram anywhere and everyone we talk to said it should be labeled somewhere. Any chance you know how to find which coil is which or have a diagram?
