To make any meaningful comments I'd need to know if you tried the easiest things first.  If the engine is running too rich, did you turn down the mixture control? If so, what happened?  If that wasn't enough, did you reduce the injector flow rate? (mode 3).  Is it rich at every throttle setting or just a few? 
 
Sounds like something has gone bad with wiring on the coil test issue.  Sounds like you still have power to the injectors when you turn the EC2 off causing it to continue running.  Correct this right away if so.
