Re: What exactly is a coil pack???
Shamelessly pulled from a website....
<i>The coil pack replaces distributor caps on "new and improved" ignition system. Instead of having a rotor and distributor cap "distribute" the ignition spark to individual cylinders at the right time and order, the spark is controlled electronically though the electronic ignition system. The coil pack is where the actual electrical current (spark) is sent to each spark plug via the wires.</i>

Here's a good article
Essentially it's eliminating the distributor and high voltage wires to the spark plugs by placing individual smaller coils directly on top of each spark plug. The coils are responsible for generating the high voltage from the low voltage battery. They run hot and can fail for a multitude of reasons...<ul><li><a href="http://www.aa1car.com/library/2004/us20406.htm">Understanding Today's Multi-Coil Ignition Systems</a></li></ul>
