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.

Don't buy from these losers. They won't stop sending you junk mail. Even though you repeatedly ask them not to. Take my advice. Pay more somewhere else

Ignition Coil
2005 Ford Escort v6, purchased at 159,000 miles for beater car. No codes but it shuddered at highway speed especially pulling slight grades. First I replaced three coils in the back and it improved enough that I went ahead and replaced them all a month later. Most of the old ones looked to be the originals. I was satisfied changing them made a difference. I also ran one quart of automatic transmission fluid through a full tank of gas. In the first 15 miles it improved some, so that was worthwhile. After replacing the last three coils I ran an other quart through, it made a slight difference, so it was worthwhile. The engine still has a slight shudder. I also power flushed the transmission for the first time and it smoothed out some. 17 mpg is the best it gets. The new coils definitely helped. For an old car I like it, the mileage sucks. I remember my 1970 Toyota Corolla getting 32 mph running it through the woods like a dune buggy. Just could not kill it.
