Q: CAN A BAD IGNITION COIL BURN OUT THE COMPUTER on 1999 Lexus ES300

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
#4 COIL WAS REPLACED TO ELIMINATE A MISFIRE, & LASTED 2 WEEKS, UNTIL THE MISFIRE RETURNED. REPLACING THE ECU FIXED IT PERMENANTLY.

This is conceivably possible. I haven't seen it myself, but electrical items can feedback into the module and destroy them, and coils produce very high voltage, so it's very possible in this case. Is it still operating OK?
