Ok as long as they were properly gapped we can run that out. Why were the coils replaced twice was the coil the original thought of why it had a misfire.

the mechanic ran a test and that what it was the error so he replaced it and it was OK for about 350 miles and came back with the same thing he replaced again and in about 400 miles same thing again

Poor electrical grounds at the engine can cause coils to burn up. There will need to be testing on the coils electrical system as well to verify proper voltages
