Wow, I have replaced many coils.......some with way less than 100K on them.....
Spark tester detects them easily......replaced more on 3.1/3.4'*, than on 3800'*, but I have replaced a lot of them.....before the 3.8'* went to 3 individual coils, we were replacing those Single Magnavox coils all the time....while 3 coils was a huge improvement, they still had failures....
In some situations, the coil was replaced because of arcing between the ignition wire and the coil terminal....so bad that sanding/cleaning the terminal, made a poor connection with the new wire....and usually led to a comeback later on....
