Not sure if it is the same problem but I spent weeks trying to find a similar issue with my 82 380SL that turned out to be cracks in the air chamber which could not be seen and my duty cycle was at 90%. I only found it after doing a smoke test. The cracks were allowing additional air into the system which told the system to add more fuel. Unfortunately, I had replaced many unnecessary parts in the process. if you think there is a chance it is the same issue there are posts on this site with photos.

Did yours fluctuate at all, or was it permanently on 90% ? Mine is permanently on 90 (or 9% if poles are flipped), regardless if car is on or key on engine off.
I am trying some more tests this evening & tracked down a newer idle control valve. The ICV which I have clicks, but testing my current unit seemed a bit off.
