Question Fixed Lambda Redaing of 20

My 1988 300SE has a fixed duty cycle lambda reading of 20. I've searched the archives but can't find anyone who asked this before. What does this reading indicate? The O2 and coolant temp sensors have been changed but I'm still reading a fixed 20 and still running rich.
