Ignition Coils Keep Failing

Ignition Coils Keep Failing
Thanks in advance... new user here. My ignition coils have failed twice. They seem to fail when I take RPMs close to redline. I was getting the 'cam position sensor' error, and learned on this forum that it's usually an electrical issue. All wires and plugs are new. I replaced the coils (and ignition pack) and car ran great. Then, when I got close to redline again, they failed again. Could this be an ECM (PCM) issue? Or a solenoid failing? Thanks!

That would be good information to have.

After approaching redline, the car was sputtering, seemed to lose about 1/2 power and was struggling to stay idling. It seemed like two cylinders were down. I replaced all plugs and wires with no improvement. I replaced coils and coil pack, then car ran great for a while. Until redline was approached again. Now, it seems the new coils are cooked. Trying to figure out what could cause that.

I don't have a clue. Does this car have a rev limiter by any chance? That would explain the cutting out and missing at higher rpm's, but not the decline of the coils. This is beyond my comprehension as I don't know much about electricity.

Heat? Coil Packs are converting high current low voltage (incoming) to low current high voltage. Along with high current often comes heat. You may be drawing sufficient current at those rpms that the coils are actually overheating to the point of damage. Though you'd think the feed to the coils would be pretty constant. So maybe I dunno.
Yes there is a rev limiter and that explains the sputtering at redline.
Any SES light action after the coils fail? If you actually had cylinders misfiring they would show up as codes.
Gotta ask this -- what is the impetus for running at or near redline?
