Other then no spark? How about problems when the engine is under load? Could it cause misfires? I mean lets say it is not completely shot just not functioning 100%

Get a spark tester and test for good hot blue spark.
The kind that has a good snap and jump to it.
Always test after engine is good and hot.
A coil fails more when hot.
