If you are talking to the DM then you have an HFM car. The CS2000 seems to give lots of useless codes on 104 HFM cars. I have experienced it twice and double checked with other tools and found them bogus.
Just a word of warning.
Did you replace the connectors beneath the coils. We are replacing them every plug change because we see so much problems.
The CS2000 should give you an actual value screen that gives firing voltages and burn times. It is pretty good at telling plug end problems that were easy to see on old dist ignitions that were easy to scope.
