Ignition coil pack replacement

The ignition coil pack replacement is an inexpensive part ($20 aftermarket) and simple installation. It only requires (2) 10mm bolts to be loosened/removed and (2) wires/cables to be detached by hand. The coil pack is located in front of the battery on a 1993 Eurovan. Symptoms that my Eurovan was experiencing was poor running, bad starts, misfires, etc. There was a noticeable difference on the short/15 minute test drive I did after the coil pack installation. As the the resolution of the symptoms, I’m not expecting this to resolve everything, but it does seem to make a difference.
