What would cause me to have to replace several of the same ignition coils in less than two years time? It seems like it always happens after I purchase gas.

    It's not very likely that the coils failing have anything to do with refueling, its a common mistake to look for some kind of association like that. Exactly how are the coils failing? Is the secondary (high voltage) insulation failing? Is it a coil driver failure when it happens? What brand are you using? Is there any other drivability issue, and/or trouble code setting?
