O2 sensor should be at the cat... the precat if you have two of them... which is closer to the engine.
The Air flow sensor is the flap you see when you open up the air filter housing... the round intake.
A 1973 450SL uses EFI, no air flow sensor. And O2 sensors did not start until 1980 with Lambda.....
A 73 SL don't have either...K
thanks guys
