1973 450SL Air Temp Sensor

My 1973 450SL has suddenly become a rough runner. Rough idle and misses a lot. In the course of trouble shooting, I discovered the air temp sensor on the horn of the air cleaner can. When disconnected, all seems fine. But reconnecting the sensor brings back the rough idle and misfire. What does this sensor do and should i just replace it?
