Have any of you folks had to replace a coil pack? If so, how did you troubleshoot your problem to arrive at this component? I have used the search feature and have not found the part number for a new coil pack for the 90SC. Not saying that it does not exist , just that I did not find it. What years will work, also, are their other Ford cars that use the same pack? Someone told me that a coil pack from a Taurus/Sable v6 is the same..... don't know.
