I agree.. The posted procedure is actually harder to read than to do..I just posted the full procedure if anybody with HFM really wants to know how to get a close check w/o a DSO wave pattern from a scope... by simply removing or adding a couple of vac hoses at the engine while watching the 02 sig.
I use/have some nice equipment , but I try to give the DIYer the same diagnostic abilities using what he would mostly have in his Tool box..which is usually just a DMM , with maybe freq and duty cycle at the most...
So, I have to tone it down, but at the same time try and get the general idea across..
With the 02 sensor wires right there under the rug, it is a simple matter to hook up and monitor while driving..some guys hook a permanent meter right on the dash. Some also use that connection to hook those a/f mixture Led readout gauges you see around.
One thing that should be mentioned on 02 sensor replacement on this or later Benz chassis [ both OBD1/2] is the fact that using a generic sensor
will cycle fairly well for fuel mix control, but the other systems [ Like AIR] require the correct relacement OEM b/c they are capable of reading the ultra lean conditions the ECU looks for on Emmissions mandates and if one does not use a sensor with this quality and precision, he runs the risk of codes when the ECU does its self testing procedures.
We will see what happens when you change out the connectors...
See ya
