Couldn't agree more. After spending the summer wading through various CIS issues (I had more than one) I now have a better understanding of and comfort level for CIS. Now if I decided that I wanted to have a 600 hp engine, EFI is the only option. A properly tuned and maintained CIS is a cost effective system for many.
Dan, when analyzing engine failures, it's difficult to arrive at the absolute cause with 100% confidence due to the extensive damage that occurs. I'd suspect an injector issue as the root of your problem. My car is a little younger than all 930's at 20 years old and I've had to replace all of the injectors due to issues with poor spray patterns and leakage.
