Bigern, I just had one doing the same thing to me. The alternator was charging at almost 17 volts. Was eating coils and ignition modules. I put 7 coils and 3 ignition modules on unit before I figured out the alternator was overcharging. Im not saying this is your issue but it might be worth checking. Also check engine grounds.
