Replace coil packs on a Lincoln

You have 2 coil packs. So unfortunately the one bad coil is not serviceable you have to replace the entire coil, but I can tell you that it is easy to do a few bolts and your out, they are even numbered, just make sure that you mark your plug wires properly.

Also if your getting 10mpg after a fluid change they did something wrong. Soemthing was not hooked up right or was knocked loose. Take it back in to have it looked at =)
