Question Question about using air flow sensor plate for base line testing

Searching through the archives, I saw where it was recommended to use the airflow sensor plate as sort of a basline for fuel system trouble-shooting.

In one thread, Steve Brotherton recommended to a fellow in Russia that he start the car, then depress the air flow sensor plate. If the idle improved a lean condition existed; if it got worse, the system was overly rich. The auto in that post was a pre-1980 model. It's my understanding that 1980 was the last year that one could "tinker" with adjustment screws.

My MB(described in my signature) is "non-adjustable". Yes you can turn the 3mm allen screw, but in another thread, Steve Brotherton cautions against this - lambda will adjust back unless you've really screwed it up.

I have no intentions of turning screws and my MB is running fine. I'm just trying to educate myself.

Would this airflow plate depressing test also apply to post '80 MBs..ie..KE-3 and KE-5 cars as well?

Thanks for your time.
