The hole for the oxygen sensor on the early W201s was fitted to the exhaust pipe - first bit past the exhaust manifold.

I can see that the fuel pressure regulator on the front of the mixture control unit does not have the vacuum hose fitted between it and the pipe work from the engine breathing pipework. This will not only mess with the fuel but the air going into the mixture unit.
