The ignition coil is a crucial part of your ignition system. It's function is to convert the 12 volt power of your vehicle's electrical system in to 35,000 or more volts. This produces a high intensity spark at the spark plug which then ignites the fuel in the cylinder. Coils in general will wear out over time. This will cause a misfire condition. In engines like this with one coil per cylinder you can diagnose a coil by putting a timing light on each one to make sure it is lighting the light consistently.

Did not last.
The ignition coil arrived within a few days and was very easy to install. I replaced the spark plug at the same time and installed the new coil. It seemed to work perfectly. After two weeks, the check engine light came back on. Took my Mercury Mountaineer back to my local Ford dealer and had a diagnostic done and came back that the same ignition coil was bad and misfiring.
