1987 BMW 635 erratic idle and no power


Suddenly my 635 has an erratic idle and wants to stall when I try to accelerate. It is as though it's not getting fuel or air. What should I check first? Some posts say 02 sensor, some vacuum, and some say air flow meter ($$$); what do you think?

I am not fond of throwing parts at cars to fix them but you may need to replace a worn air flow meter to start with. Let us know if this works.
